Which should deal with the echo cancellation issues, provided a
conference bridge, say.  That should work for remote presenters.

For other remote participants a VOIP teleconference system would be
great.  We do this all the time at Sun internally for large meetings, so
it should work.  (The IETF might have to charge remote participants a
conference call fee, if it uses a third party provider, say.)

My point, however, was that one way to solve the id-at-mic problem is to
make the problem symmetric for all participants :)
