if other codecs are being discussed (H.261/3, Theora), it may affect the
traffic model discussion in RMCAT , i.e., how much variability in
sending rates can be expected for a target rate and how quickly can the
codec respond to a new rate request.

If the expected behavior is very different from the discussions on
traffic models (in Vancouver), having those discussions helps us
understand the congestion control requirements better.
