I think coming to terms with these two major scenarios is what this task
force is all about.

You obviously bring a lot of prior context to this discussion. As a relative
newcomer to the scene, it would be very helpful to me (and others I believe)
if you shared any relevant mailing list discussions that could help bring folks 
like me up to speed on the WebRTC group's current thoughts on the MediaStream 
and how it is viewed from the RTC point of view.

For example, what's the "stream of bytes fallacy", and why is it a poor view
of a MediaStream? Also, would love more info on what you say just below:
