Well, as there are no other API proposal that exists in the W3C WG
currently I don't know what else I can use in the examples.

But in fact what is needed is a signaling channel between the peers that
can carry a list of RTP Session:SSRC value = label value. I think that
can be applied to a number of different signaling and API alternatives.
