Hi Matthew,

>A few questions raised by this thread:
>
>1) Did the discussion about “trickle ICE” actually turn into an I-D for (I suppose) MMUSIC to look at?

http://www.ietf.org/internet-drafts/draft-rescorla-mmusic-ice-trickle-00.txt

There has been some discussion on the list already.

>2) Are we seriously considering defining the allowed SDP for RTCWEB/WEBRTC by referencing an I-D and not an RFC, or are we going to delay defining the allowed SDP until trickle ICE is in an RFC, or are we going to drop trickle ICE from RTCWEB 1.0?

I guess the same question applies also to BUNDLE, and potentially to a number of other I-Ds.

>4) How does trickle ICE work without “relaxing” RFC3264 O/A? It seems like you really want to be able to trickle via updated offers that may be generated prior to the corresponding answer or reject? 

One of my comments on the trickle draft was about that. The draft says that a new offer can be sent "at any time", but my comment was that it should be according to 3264.

IF we are going to relax 3264 (I really hope we are NOT), it needs to be clearly described somewhere. We cannot have a number of I-Ds doing it "on the run"...

Regards,

Christer
