Dear All,

like too remind that there are three first WebRTC data channel applications, 
1) MSRP based instant messaging, 
2) T.140 based text conversation and
3) BFCP based floor control within a WebRTC conference service.

draft-ietf-mmusic-msrp-usage-data-channel was/is the precedent for getting a common understanding about application protocol specific SDP usage (on top of the generic control of a DC).
The discussion and protocol design are fairly mature in the meanwhile, hence it is time to start the work on the two other applications.
We've prepared initial drafts, derived from the "MSRP draft", see:

T.140 Text Conversation over Data Channels

BFCP floor control signalling over Data Channels

We'd like to request MMUSIC for adoption of these drafts.

Version 02 of draft-ietf-mmusic-msrp-usage-data-channel addresses Christian's comments to version 01,
except for the "setup" attribute related one.

We'll come back regarding the SDP setup attribute, which can be part of an MSRP over data channel
related SDP media description as media level "a=setup" attribute and/or as MSRP sub-protocol specific
attribute "a=dcsa:x setup".
