It seems like we have a transport problem :-)

The issue is that with people closer together, the RTT between people is
shorter, and the chair does not get a chance to do congestion control, and so
goodput gets too high?

In order to accomodate large RTT remote participants, we need to slow down
the DC-speed traffic in the room?

But, I note that in the current presentation-style setup, we often do not
service the remote queue fast enough already.  Maybe the U-shape room simply
makes this obviously a problem.  Maybe we need to accomodate remote
participation in a more asynchronous nature, rather than in the CB-radio
way that we currently attempt to do it.
