You answered my question very clearly, thank you. This sounds like a nice
feedback system using the rotation sensors, and could be used to signal a lot of
things. Do you use a single axle connecting two rotation sensors where the axle
can be turned by either RCX (this would require two motors and two rotation
sensors), or does each RCX have a dedicated output system and a seperate
dedicated input system (this would seem to require two motors and four rotation
sensors).
I assume the RCX collecting the points would not have trouble with
simultaneous IR messages because only one "scoring event" would happen at any
one time (the ball could only hit at most one target or scoring device at a
time). Did the point collecting RCX need to identify where (which RCX) the
points were coming from?

Fantastic - I look forward to seeing it!
