I haven't really looked into this but can the IR port on the RCX be used to
send out a message and then flip to receive the reflected infrared light
thereby using it as a sensor and still have 3 ports left for other sensors?

I have read about using the IR port in combination with the light sensor
but thought this might be a possible alternative.
