I don't think there is enough room for the WHOLE PGP package in the RCX,
perhaps just a single cipher, RSA key exchange and a single hash method.
Does anyone know off hand if any of these features require floating
point?  You could probably substitute for an algorithm that doesn't.

If you need floating point numbers the leJOS JVM for the RCX uses floating
point:

http://lejos.sourceforge.net

This seems like a very intersting idea. I actually wanted to skip the RCX
altogether and somehow link up a networking protocol using just the IR
Towers. One computer could communicate with another and you could even throw
in some encryption so no one else could intercept it.
