But my other group that hangs out in there async every day and the occasionally jumps onto an ad-hoc voice chat when people are available to game, or sometimes shares my screen so someone else can watch what I’m doing? None of those things do that.

And we could limp by with an XMPP room for chat and then a link to a Jitsi or Mumble or something when it’s time to do something. But there’s something tight about having the “just call” button right there, tied to the chat you’re already in.

XMPP can do actually that with the Movim client! It's able to do group voice calls, group video calls, screensharing (now with audio as long as you're using a chromium based browser), and even has a blog functionality built in :D

The Movim dev is currently working on implementing discord-like servers with rooms.
