Re: [MMUSIC] draft-ejzak-mmusic-data-channel-sdpneg and draft-ejzak-mmusic-msrp-usage-data-channel

["DRAGE, Keith (Keith)" <[e-mail]>]

At the London IETF meeting, we were not quite at the point of asking for adoption of draft-ejzak-mmusic-data-channel-sdpneg. There was a request that certain revisions should be made and a couple of issues addressed.

That has now occurred.

I would like to ask if we can now moved forward to adoption of this draft as a working group item. While it is the responsibility of the chairs to make a formal call, I have asked for a small amount of time in Honolulu with this intent, and it would be useful if people could start to express their opinions one way or other on the list, i.e. whether they think the draft is generally useful, or alternatively, just a bad idea!

Regards

Keith
