Re: [MMUSIC] draft-jennings-mmusic-adjacent-grouping-03

I am wondering about the following:

Section 3.1 "This is a declarative SDP parameter and is not negotiated."

Section 3.3 "The offer MUST contain the sender's desired layout. The answer
MAY contain the desired layout of the streams that the system sending the
answer will be sending to the system that sent the offer."

The text in section 3.3 looks like negotiation to me.  Presumably the
answering system is taking the offering system's desired layout into
account.

Also, I do not think the arrangement of audio streams in an MxN grid is very
compelling - do you have a good use case for this?  There are of course
several sound formats already available in RFC 3551, I am wondering why we
need to standardize more than that.
