It's worth noting that in that particular experiment, the round trip
time was dominated by the latency of the multicast audio feed which we
were using for one half of the link. If we were to try this again,
we'd use the VOIP link for both directions to the remote speaker, to
avoid annoying latency issues.
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.)
Perhaps Sun would like to volunteer its system for an experiment?
