Auto mixers like the Audio-Technica MX series have a useful
tally signal out which says which mic(s) is/are selected.  In
default mode only one is selected.  We use them extensively for
standard video conferencing without echo cancellation problems.

> One of the things I want to look at is using an autogating microphone
system, and use it to steer the camera(s) to the main audio source. This is
similar to the PictureTel/Polycom Virtuoso audio system. If done right it
can be very effective. There's some alternatives we're looking at as well.

The OpenMash folk did something like this too, but I think it looked at
relative microphone levels in a multi-mic system.
