I must be expressing myself quite badly, because the message seems not 
to get through.

* I think we have consensus on adding API that allows most use-cases to 
be met without SDP mangling (given that SDP O/A is kept naturally)

* We discussed last year an alternative API that did not use SDP at all 
(and did not use PeerConnection). The decision at that time was to 
continue developing the API based on PeerConnection and SDP O/A.

Have not stated anything more than that.
