If the data channel is available, why not use it for DTMF?

Imagine I was building an n-way video conference solution based on a scalable video codec, with a central point transrating each stream based on the active speaker. Receiving codec events in the javascript would enable me to detect rate changes and re-render the display appropriately without requiring a full renegotiation each time. Neil
