2 years done, 2 to go....
proof of concept for
distributed electronic payments seems to work ok, but does
not seem to have a visible market.
Ideally want to squeeze it all into a smartcard. The
test
server it runs on is not always up as it was supposed to
have migrated to a PC104 board board but getting the boot
loader to sit happy on a compact flash card is seemingly
more difficult than expected.
