Hi Sébastien.
congrats for your awesome research and work, this is truly impressive.
The little ant that I am (compared to you) was interested in helping you with the SIM aspects of the project. I think I know javacard sufficiently to implement a basic sim card that can be totally controlled. I already started to think on how to do that. This will include making host side tools, too. If javacard is not open enough, we can also look at native cards using PIC, for example. In our previous discussions, the main problem was the availability of SIM sized cards, be them javacards or not.
pros and cons
- javacard is an industry standard, coupled with GlobalPlatform specs this
is a portable way to put an application on a card without being locked with a card manufacturer.
- native PIC cards benefit from a lot of open tools such as the gp* PIC
tools, asm, sdcc for compiler and gpsim for simulation.
- some projects exists already, I don't know them well, maybe they can be
used, forked, improved.
- availability must be checked.
I'd like to request precisions on how the things should be done, what are the minimal requirements (files, etc) and when the openSim project will be needed regarding to your progress.
I only want to say that i am courrently drive a semilar project. I have developed a smartcard O/S for Atmel-Cards (license is GPL, of cause....)

Currently i am working on a simcard implementation. Currently my simcard can process SELECT commands (but not READ BINARY & Co so far).
The download link leads to the current release (which does not include my simcard source). If you are intereted to see the source of my unfinished sim project i can make it available.
I can not say when my simcard gets finished because there are a lot of other important (and sometimes more interesting) things to do.
Best regards. Philipp
