Another thought on this... I just remembered an earlier posting I made about
sensing the output of the RC receiver with an RCX. It uses a micromotor and a
rotation sensor as a "buffer" for the signal. In this way you can detect both
forward & reverse, as well as in-between speeds using only Lego components.
Here's the link (with pictures):

So, hooking up a couple of these "buffers" (one to the main RC output and one to
the auxillary RC output) and a seperate rotation sensor to the RC steering servo
output, an RCX could decode all three channels from the RC receiver. (I realize
Mark Bellis' reply inferred this, but I thought the pictures might be useful in
visualizing things a bit more...)
