This sounds complicated. I'm not sure if I'd want to go hacking into the
RCX, but if you have an idea and a good idea of how to make it work, more
power to you. I'd just like to point out before you get started that the
infrared communication does not necessarily have to be line-of-sight. If
you set both the tower and the RCX to high power, you can send and receive
transmissions from quite a distance. I've had reliable success from
distances up to 30 feet, even around corners and in different rooms.
