[MMUSIC] The way forward wih mux-exclusive

[Flemming Andreasen <[e-mail]>]

Greetings

We recently went through WGLC on the mux-exclusive draft 
(https://www.ietf.org/id/draft-ietf-mmusic-mux-exclusive-03.txt). 
Following the WGLC, a question was raised as to whether we really need 
the mux-exclusive mechanism described in the draft or not. The issue was 
discussed further in the MMUSIC WG meeting this week in Buenos Aires 
which yielded the following outcomes:

- There was agreement that we should have a signaled solution
- It's important to get a solution quickly since this issue is holding 
up progress on other drafts that rtcweb is dependent on
- The only two proposals that got support were "rtcp:0" and 
"rtcp-mux-exclusive"
- Everybody in the room could live with either "rtcp:0" or 
"rtcp-mux-exclusive"
- A hum between the two slightly favored "rtcp-mux-exclusive, but 
overall it was inconclusive in forming a consensus

A couple of key participants in the mailing list discussion (EKR and 
Martin Thomson) were not able to attend to attend the MMUSIC session, 
however Christer subsequently met with them, and they they graciously 
agreed to respect the consensus established in the meeting.

Based on all of this, and since we currently have a WG adopted draft for 
rtcp-mux-exclusive that went through a WGLC already, we want to continue 
with the rtcp-mux-exclusive solution. If anybody objects to this, please 
let us know no later than Friday, April 15.

Thanks
