I asked about SDP, not WebRTC. The thing that is making this take a long time is you don't want to use SDP.

yes, that is defined for SDP O/A

> Has glare been solved?
yes

This is obviously trivial if not using bundle. Any version of MSID would work. It's only complicated by bundle

I disagree. They are only unresolved because we want to add bundle and that was a major change to RTP resulting in a bunch of work needing to be done to see how that impacted SDP.
