I don't want to restart this debate, but I'll point out that it's very 
useful for situations where you're using timeslotting, or for balloons 
that won't ever get an open channel anyway.

A customer just sent me a screenshot of a racetrack with several 
OpenTracker-equipped vehicles being tracked at intervals of a few 
seconds using timeslotting.  None of them have any need to listen to the 
channel, and there are absolutely no collisions.  None of the packet 
kind, anyway - the other kind depends on the drivers!
