     I asked the same question (why isn't video implemented on top of 
DataChannels). If I remember correctly, the answer was interoperability. 
Meaning, anyone with a legacy system already parse SDP (different from 
ours, but still). If we placed audio/video on top of DataChannels, 
they'd have to implement the DataChannel API as well.

     My own opinion is that gateways solve all of this. We should be 
building the best API possible, and delegate to gateways to convert from 
one communication format to another. I understand that gateways have a 
bad reputation, but I believe it's mostly due to the fact that they were 
used for video transcoding in the past (which limited scalability). 
Protocol-adapters are cheap. They can come in the form of a gateway or a 
small library you integrate with. Just publish a public-domain protocol 
adapter as a library, and let people integrate with it. That seems a lot 
less expensive than mutilating the API.
