I think that the question is whether it should be possible using
constraints to reject incoming streams.  That would provide the
symmetry that we are looking for here.

InboundAudio: true and InboundVideo: true as constraints would work, I
should think.  They could apply to offers (in that they would trigger
the creation of an appropriate m= section.  And in answers, they would
shape the characteristics of the response: a=sendonly or m=audio 0.
That's not perfectly symmetrical in the latter instance, you could
always create the streams and use a=inactive, but that seems a little
wasteful, especially if we aren't bundling.
