Subject: [clue] Design Team meeting tomorrow 21-aug @ 9am CDT (GMT-5:00)
Precedence: list

We are going to try to hold the design team meeting tomorrow.
Mary can't make it due to a travel conflict, so I'll be chairing.
But I think webex will still not work for me, so somebody else will have 
to grab the host role initially so that we can share. Mary is rounding 
up somebody to do that.

There is plenty that needs to be worked on, but lets try to focus.

One issue is ticket #11 (http://tools.ietf.org/wg/clue/trac/ticket/11), 
which has been in discussion lately. We have been having some discussion 
precisely on the ticket - is the extension needed? Or could the problem 
be solved with the static SSRC mapping. A different point came up in 
Vancouver (by Magnus or Colin) of whether its legal to use an RTP 
extension header to carry info that is essential to the functioning of 
clue.

I'll pose four questions to discuss tomorrow about this:

- can CLUE *work* without a dynamic mapping of RTP stream to
   capture+encoding pair? (Hence the requirement for an RTP extension.)

- if so, how severe are the negative consequences of doing so?

- can the capture+encoding information be conveyed with RTP in a
   way that is legal according to current RTP standards?

- if not, how difficult and timeconsuming will it be to update those
   standards for what we need?

If that doesn't take all the time, I'd like to discuss how to get work 
going on clue transport, beyond draft-wenger-clue-transport. It seems to 
me that we are just denying the inevitable. I'll propose a stake that I 
would like to drive:

- the CLUE transport will be the SCTP/DTLS/UDP stack that is proposed
   for RTCWEB.

So I'd like to hear any arguments about why we *shouldn't* drive that stake.

	Thanks,
	Paul
