Hi,
About the remote hub I think it would be good to give it a try.
I'm increasingly intrigued by this idea. It could be interesting to
try to formulate a serious proposal for this, with enough detail to
qualify as a functional specification. The easy part is specifying
audio/video streams support. More challenging is to get the personal
and personnel support figured out.
I think most of research/university networks are facing same challenge.
Remote class setup is exactly what we need (with support of back a/v
channel). Not a rocket science, but can be expensive in case of support
in number of parallel tracks.
There is also a question if IETF wants to cover only room-to-room setup
or want to cover room-to-desktop scenario.
And should it have some means of assisting discussions outside of the
bof/wg/plenary sessions?
Having a mechanism for "voting" has also some value.
