Re: [rtcweb] Basic scenario 'impossible?' to achieve with the actual API

In order to avoid the exposed circumstance, where a user has to 'suppose'
she is sharing her media because there is no way to certainly know, yes,
the JS application should be able to, at least, check if a localMediaStream
is being transmitted out of the RTCPeerConnection.

This would be a simple task if each mediaStream, or mediaStreamTrack had
it's own associated (even if logical because of Boundle) transport. In that
case, such connectivity status would give the information and much more
control over each media element.
