Have the Tower always start a transmission with N. When the RCX sees N,
ignore any light sensor spike until the Tower stops transmission [fixed
length transmission or until it sees a stop number M].
What would give no indication of distance? To what?

Yes, but even if that was posible it would give you no indication of
distance.

With this IR Radar stuff is the reflected signal that is picked up by the
sensor also strong enough to be picked up by the RCX? if so....
Send Out a number N,
If the sensor thinks there is something close then
if last number received via IR port == N then
it's probably us
Change N
Repeat.
If you change N randomly and sample several times before making a decision
then you can be pretty sure that it's your own reflection you are "seeing"
and not a tower or hostile RCX :)
Cheers
