(I haven't used it, just browsed documentation. My questions are based on no experience.)

This looks really cool. I've done a couple live coding streams with someone working with me as a sort of collaborative effort. I see a lot of potential for this replacing live streams for this sort of thing. Do I have to know every guest? Can I provide a link for viewing guests to access?

It looks like the current implementation is either fully open or read-only for all guests. There seems to be no way to ... "assign roles". Am I wrong?
