I have some minor corrections:
Remotes: Transmit Only. Modulation Frequency approx. 40Hz
Remote Receivers (little silver boxes with 68332s): Mod. Freq: 40Hz.
Sharp Tranceivers: Receive or Transmit. Mod. Freq: 500 Hz.
Newtons: (have sharp tranceivers inside of them.) Receive/Transmit
Mod Freq: @ 500 Hz.
The above are non-configurable. They cannot be changed.
You have to have the modulation frequencies match to send or receive.
IR remotes match IR remote receivers.
Sharp transceivers have both a send and a receive unit, and match the
Newtons.

[REPLACEMENT FOR ABOVE PARAGRAPH]
The Motorola 68332 computer is very flexible, and could easily talk
to a Sharp Transceiver in addition or instead of the current remote
receiver. This would involve some small amount of hardware hacking,
and some software hacking as well.
However, if we all agree to send RS232 over the Sharp Transceivers,
you don't need the 68332 at all. Instead, you connect the Sharp
Transceiver directly to the Newton serial port.
Same goes for the PCs.
