I don't really have any input for the technical aspect of this, I just
wanted to say that this sounds like a TON of fun to do.  I don't see
why it wouldn't work.  I have messed with the NComputing stuff a bit
and this sounds simular, but open!  Good luck and keep us up on how it
goes, I am for sure interested to hear about the end results.
