Ok, here's a real hacker's hack.  I've played around with raw IR readings on
RCX under BrickOS (ignoring all protocol stuff).  You can basically get it
to read _something_ with any light source that triggers the sensor.  I
suspect it's a typical 1-start, 1-stop, 8-bit async uart.  So in theory, you
could read signals with say 50 or 100 us timing, but you would only get one
or two readable bits out of each byte (in practice, certain ranges in the
byte read would indicate a zero or one).  Nuts maybe, but could enable you
to pass messages from NXT to RCX.

Just a crazy thought...
