I believe in the video (yes that video) they said it uses peer to peer communication, so technically it is perfectly possible. I do not know, of course, if it’s possible this time around, but see no apparent reason why it wouldn’t be in the future.
What would be really cool, is to have a folder like, that is a peer folder, track that contains one or more audio tracks as shared by a peer (maybe even a video track), that can then be recorded as needed. You could of course be represented similarly on the other end. If you could then instantiate more peers this way, that would pretty cool.
