a) The Phones (Ericsson, Nokia, Motorola etc. )
b) The Transmission Standard (GPRS, HSCSD etc. )
c) The Telcos (Swisscom, Sunrise, Orange et.al. )
Roger does not have the same Telco as I have; so my first thought was, that it is simply a question of the provider. Your experiences, facts and comments on that topic are kindly welcome.
Chregu pointed me to a posting  where it is stated, that the down- and upload performance actually depends on the phone. That is still not satisfactory since the weak upload rate is at about 12 kbps (about 1.5kB/s ) which is still five times higher than the rate the T68 reaches (20kB/60s is approx. 0.33kB/s). Maybe it is too hot for maths these days.
Furthermore attached images will be usually encoded by base64 and therefore increase the size by about 30%; this of course for both the phones.

Jennifer Golbeck  et. al.  have written a paper on "Trust networks on the Semantic Web" which affiliates seamingless to the above thoughts. Eric Vitiello Jr. [4,5] describes "A module for defining trust relationships in FOAF":

Weblogs are said to be "A web site organized by time", a diary with reports, news summaries, random thoughts, interesting songs, pictures etc . The time factor is mostly part of the URL of a specific blog entry, also there are variations [see Joi' URL, 1]. Entries are furthermore organized by one or multiple categories . Even providing an archive does not prevent from searching for a certain entry, which leads to a search engine to be implemented. Weblog entries often can be commented via a comment field or or ping- or trackbacks. I would rather like to have a weblog with a forum attached  than a simple guestbook-style comments collection.
A Wiki  is a web-based writing space and is typically collaborative, but does not have to be. While weblogs basically store events, Wikis categorize data . Furthermore a Wiki has revisions of pages .
Combinations are already fact ; Joi does it, others too - see site of Andrew, Keith, 0xDECAFBAD et. al. I also makes sense to crosspost links or contents to existing Wiki titles. Andrew has a hack:
I now also have a hack to B2 that automatically inserts links to wiki pages (with wiki names) that exist, but only if not in between angle brackets - I don't want to have links inside of links as nested anchors haven't been allowed for a long time in HTML land.There is currently a discussion over a package called "Text_Wiki" to handle Wiki-like markup  that could make such an integration less painful.
Some more thoughts and discussions in this direction, leading to klogs:
16. July 2003JavaOne technologies at present and in future to be implemented in mobile devices.
The main element of this package is a location provider that delivers the device's current location to the application. [..] This API not only will enable "what's near me" restaurant services, but also could be the basis of some cool games. http://www.circle.ch/blog/p970.html
Just found that site  via the "Related Links" engine:
The Alternis Location Mediation System (LMS) allows mobile network operators to develop and offer personalised, private, billable applications and services with no adverse effect on network performance or quality. http://www.alternis.com/overview.php
USA TODAY obtained government and corporate documents that provide a rare insider's look at Microsoft's efforts to keep from losing a key customer. Among other things, it: usatoday.com/money/industries/technology/
15. July 2003LinuxTag 2003. I was also exited how difficult and bewildering it must be for English speaking folks to talk about the "Swiss International Air Lines AG" ; Swiss, Swiss Air, Swiss Air Lines in its shortform? Time Swiss gets merged into Lufthansa .

The whole thing is very GPS oriented, which kind of puzzles me [..] So I will have to ask someone for a GPS device to try it myself [..]
As far as I understood that background, it is about getting localized information from mobile gadgets as on tokyotidbits.com [location info, 2]. As I have no GPS around here and do not at all intend to carry one around with me - at least as a seperate tool - I thought that there might be a way to get some localized information out of the mobile phone.
At least on my mobile phone and with the telephone company's help there is a way to get the "Zelleninfo" (Cell Broadcast, CB )  - an information about the place of the most closest antenna, or at least the one with the best signal. You can most probably enable that bit of information to be displayed on the phone via a subcategory of the SMS menu.
So, what we get there, is something like "BERN WEST" - far from being as precise as a GPS. But imagine to combine such information with moblogged images; that would result in an interesting track along your image gallery.
But how can we get that info out of the phone and back to a webservice. CB is a monolog. It works from the emitter to the receiver (mobile phone). As long as there is no way to attach that localized info directly to an SMS or something, your hands are tied. Ok, there might be a way to hack the mobile software or writing a java application maybe. Is there a workaround?
Maybe, if we have a look at the WAP protocol . What about this way?
10. July 2003HasciiCam  makes it possible to have live ascii video on the web. It captures video from a tv card and renders it into ascii , formatting the output into an html page with a refresh tag or in a live ascii window or in a simple text file as well, giving the possiblity to anybody that has a bttv card, a linux box and a cheap modem line to show a live asciivideo feed that can be browsable without any need for plugin, java etc.

This technology needs to be discussed. RFID offers lots of advantages compared to a simple barcode. Starting from here, RFID transponders can basically cover the same functionality as barcodes but depending on the integrated features or algorithm within such a chip there is more to come. RFID chips e.g. can not only carry a serial number but also memory like ROM or EEPROM to read or read/write data to the chip.
Since most of these chips are passive and have no internal power supply they do nothing unless they are asked for. So you need to have a reader or a basestation that emits energy via radio waves and simultaneously communicates with a single or multiple transponder chips. Common frequencies are 125kHz and 13,56MHz. There are trends to other, mostly higher frequencies though.
Having that technical information in the back of one's mind it is kind of obvious, that if such systems want to be successfull in a global spectrum, it cries for standardization. Communication protocols and chip specification need to be based on common sense. If an Italian teacher talks to German pupils, they will not understand each other unless they find a compromise.
So privacy concerns are legitimate if such a uniformed techonlogy will spread globally. And to come back to the barcode, it is hardly to see why this should not happen.
Among the amusement facilities is Ocean Dome, one of the largest indoor water parks in the world that can accommodate 10,000 people. A sliding mechanism allows the roof to be opened or closed. The dome is 38 m high (41.8 yd.), and encloses the area 300 m (330 yd.) wide and 100 m (110 yd.) deep. Inside, there is a man-made ocean with waves and beach, and a mid-summer environment is maintained with the air temperature at 30ºC (86ºF) and the water temperature at 28 ºC (82.4ºF) all year round. http://www.jinjapan.org/atlas/architecture/arc27.html
