Ummmm.... Part of the issue is that with multiple participants with multiple inputs and outputs, you can't send all inputs from all sites to all other sites. You kill the network, so some judicious control of what is sent when and to whom is needed. That means that some inputs (microphone or camera) are not transmitted at times. So, do we allow legs to be asymmetric or not? Interested in your view of the collective impact of these types of control decisions.

In the case where the receiver elects to get three separate streams, then I have a refinement for my question. Who now decides how the streams from A map on to screens at B? A could send streams targeted at specific screens at B (after examining B's description of it's screens) -or- B could send A instructions on where to send each stream (based on examining A's description of it's cameras) -or- We can find use-cases in which both techniques might be required. I am trying to decide how complete the information in a room description really needs to be. While I like the idea of a reasonably complete physical description (since it is very future proof) - I think it imposes a burden on each side which might not be warranted. The other extreme (just label cameras left, center, right) seems to obviously limited. Where is the middle ground? Peter Musgrave
