The most interesting thing for me is actually the galene server, but playing around with the demo server and looking at the documentation it seems to be a fair bit behind Jitsi in ease of use and deployment.

(I built a one-shot template to deploy and run Jitsi on Azure - https://github.com/rcarmo/azure-ubuntu-jitsi - and it's been trivial to maintain over the past two years, for a small group of friends and monthly "open sessions")

I'm not enamored of the Pyrite UI (again, Jitsi seems simpler), but I'll keep an eye on both.
