[liberationtech] Opensource SDK for SIM hacking

Jacob,

After digging in to these projects with the team, I've got a better answer
for you.

The low level C work is great and portable, and it may be something that we
can contribute to and leverage in any of the solutions that we produce. The
fact that the higher tiers are in Python is both good and bad. Basically,
it would be difficult to side with Python 100% as it would rule out all
unmodified Windows systems to run the software - as in no windows
distribution comes with the Python runtime and anyone who wanted to use OSK
would need to download Python first. This is probably fine for developers
but no so much for the everyone else.

Kennedy (a contributor the project) came up with a lovely idea
for incorporating support for several different host OS's: Basically you
download OSK to a USB key, when its inserted into a computer it checks the
host for things like Python, Mono, etc. and then launches a version of OSK
that can run on the host.

For us its really about being able to offer support for as many different
platforms as possible and as many different device connection options as
possible (AT in addition to APDU) to lower as many barriers to entry for
the solution as much as possible.

Almost all of these projects are 100% developer focused.  Our goal is to
make the environment more friendly for developer and the end users who
aren't.
