Dialogs are entirely SIP level concept, but what I am arguing is that with
ICE and WebRTC you can associate RTP streams with a particular answer. This
means you can clone connection, provide it with the answer and each
connection would be able to filter out only the media that is intended for
it. If I am missing something and ICE is not enough then msid should be.
