Another case would be where you also want to use IR for doing radar. If you
had IR messages bouncing around for both radar and communication, it might
confuse the radar algorithm or generate incorrect readings. (You'd also have
to reserve a message number for the radar ping that wouldn't be mistaken for a
communication message.)
A third case might be in robotic combat scenarios, where you might want to
avoid opening the door for one of your opponents to send bogus control
messages to your RCXes to confuse them. While this would be a somewhat uncool
tactic, all's fair in love and war.
But these are all pretty unlikely reasons. In most cases, IR messaging is the
way to go for inter-RCX communication.
