The APIs being discussed now deal with "MediaStreams" that contain both audio (zero to many) and video (zero to many). This has been found to be a reasonable level of abstraction for the web app developer. The web app developer would have difficulties to understand how many RTP streams a MediaStream would generate. So it is not so simple to deal with this by creating several peer conn objects. Besides, it has been discussed that A/V synch should be maintained within a MediaStream. This is something you would lose if you split it up and transport it using separate peer conn objects.
