Thank you.

Can you comment on how reliable it is?

It seems to have a limit of 24 users, and says it might not work on mobile past 10 users.

It works well past 10 users on very high powered mobile. Less so on cheap phones.

It's really more that you are spraying high volume websocket and webrtc data continuously while doing realtime 3D/WebGL - you are practically running a full game at this point.

After reading through the documentation and poking around in the UI, I didn't see any way for participants to stream their webcams. Do you know if that's possible?

I don't think we want a VR teleconference, we want to see each other.

It is a pliable in-game object, you can throw someone's screen, resize it, etc.
