Concerning the sw-only solution using just an IR receiver. That software seems to be only looking for Sony IR codes. How will that work with a bunch of teams at once? If everybody selects Sony, things will get very interesting.
Good luck,

You should make sure teams know what the valid input voltage will be with the added diode drop. Will they be able to use the ~7 volt PWM outputs? How about using a LDO regulator? Perhaps eliminate the regulator all together and have a pinout that allows teams to use the RC's 5 volt output?

Um, are you saying that you can somehow remove the interference in software or by choosing a different protocol? My suspicion is that there is zero difference between the software only solution and the IR board solution. Both are subject to interference because they both use the same Vishay IR detector and both ultimately do the protocol decoding in (PIC) software.
