congestion control in FLUTE

Hi,

As FLUTE is an application of the RMT building blocs I think it needs to 
specify how the hell you actually apply some congestion control on the 
sessions. In section 4 there is discussion about four scenarios of how 
this may be done. I think it will be necessary to flesh out how one 
actually perform A and C using the available tools. That means 
specifying how you actually can apply WEBRC and TFMCC to flute and what 
restrictions that do apply. It might not be necessary to define both, 
however we do need something that works well in most deployments where 
FLUTE is used.

It would also be really good to see someone write up the glue that is 
need to enable implementation of WEBRC. There seem to be need for 
clarification on how to handle the WEBRC channels and in addition how 
one signal this to the receivers using SDP.

I want to get this going as I don't think we will be able to proceed to 
standards track with flute unless we have a solid congestion control story.

Cheers
