I'd really like a self-hosted videochat solution that had a native client. Basically something like Mumble (https://mumble.info) but for video.

The reason I want it is because most large videochat solutions have a really high variance in latency and reliability. If I just want a small group chat with friends, I'd have far fewer issues if I just self-hosted. I've already found this to be true for Discord audio versus self-hosting Mumble.
