Hi Giancarlo.
I think you can't avoid phisical interference between the IR messages of the
two teams, because there's no way to change the carrier frequency of the IR.
With the RCX 2 firmware you can change it, but from what I understand this
affects only the "Serial" group of functions that are designed just to send
data packets, not to receive them. Communication RCX to RCX is still based
on the single byte messages (hope someones prove me wrong :-) ).
If 128 single byte messages per team are enough for your needs, you can
simply write the software so team 1 handle messages from 0 to 127, while
team 2 those from 128 to 255, both ignoring the ones from the other team.
