School is closed, but class isn't. Classrooms and play-from-home groups urgently need a solution for parents/teachers. What I'm looking for is a solution for classrooms or other activities for tweens (think 4th graders). I need to be able to limit the users to only those who are authorized, but leave the rooms open for joining/exiting much like a chat server. Jitsi itself is great for that except there is no white-list authorization and that I'd have to host it myself (the free host is overburdened). I think you're targeting a different use case, but schools and parents everwhere need a classroom solution urgently.
