I don't really care much about the scenario other than there are 8 streams being set up. But this type of scenario is becoming very common for multi party video chat as it allows you to see perhaps small versions of everyone plus a large version of active speaker.

[BA] Yes, that is correct.  However at the moment I'd characterize that as a "high quality problem", since it isn't even clear that the current WHATWG API can handle that case, due to glare and ICE timing issues.
