Sounds good! In case it isn't patented: I can google for the document and
download it via the links. It doesn't look like the site(s) I found the
documents on are pirate sites (I send one URL earlier) and I didn't click
on any license agreement, so if you could provide me with an include file
(and ideally with a stub c file), I would try to do an implementation of
snow-3g. It would be up to you to test.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
