have a look at the following deep link;
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1490167
We used 2 motors 2 axles and 4 rotation sensors:
one set for signals towards the newball RCX and one back towards the Points
Collector RCX.

Right only one IR message at a time.
there is no indication where the points came from, since this is not nessary

I did not have the time yet to make a nice movie please have some more pacient.
in the mean time look at this:
