I agree, and in particular I have always found the picture in section 
4.1 as confusing/misleading in that it indicates that the MediaStream, 
with two consumers, would have to be defined with two (input/)outputs. I 
think it should be changed in a way where several consumers are attached 
to the single output of a MediaStream.

Are you referring to section 4 of the "Media Capture and Streams" 
document (the name of the section is "Stream API"; it should be 
MediaStream API I think) or to the "Streams API" document by the Web 
Applications WG?
