     I understand you're reasoning, but I'm not sure I would rule out
     IR without at least doing some testing.  Consider that if you put
     the transmitter on the top of the projection screen pointing down
     at the audience, you should have a clear line-of-sight shot at
     everybody.  As for narrow off-axis performance, my experience
     (with an admittedly expensive pair of Sony's) has been that being
     *way* off-axis has never been a problem.  I'd be surprised if range
     would be a problem either.  For the size of audience I could
     afford to buy headphones for, nobody is going to need to be very
     far away from the screen!  ^_^

     Thanks again for posting your work in this area!
