That's a fun mental puzzle.  If we used public key encryption,
it would still be possible in theory.  Each person uploads one stream
to the server, the server sends all streams to all users (with perhaps
some out of band signaling for optimization).

Would have to trust the symmetric key with all members of the call,
but I think it's still possible.
