I would like to point out that the currently proposed W3C APIs do not 
require (or even allow) SDP manipulation for _any_ of this, with the 
possible exception of audio bitrate (which, as we've long discussed, 
should actually be adapted in real-time based on available bandwidth as 
determined by congestion control, with some app-provided way to set 
priorities that will _not_ be based on SDP... the number in SDP merely 
defines the limits of what's possible).
