OK - retraction time, folks.  I got fooled by the headphones HITL and Boeing
were using.  I thought it was Convolvotron; it wasn't.  Therefore, the only
Convolvotron I've seen was the one rigged up for the demo at the Virtual
Worlds Consortium at HITLab last, what?  February?

That demo doesn't compare well with anything, since it was putting sounds in
3D space without regard to users' head position.

So I take back my assertion about the superiority of Focal Point in handling
Z-movement of sound.  I don't have an adequate basis for comparison.
