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.
