One of the biggest problems with networking any number of calculators
with radio links is that no two calculators could transmit on the same
frequency. The best way would be to have a centralized hub, but thats still
two frequencies per calculator on the network. I could be wrong about this,
because Im not sure how Cell phones handle it... I think a network of
calculators is an insane idea anyway!
