Keep P2P as the default for small rooms — that’s most servers most of the time and the no-extra-infra story is genuinely valuable for self-hosters.
[I] went mediasoup, built into Haven, after all. The two things that pushed my plan above toward LiveKit are gone now. It runs on one port instead of a whole range, and it downloads a ready-made build instead of compiling anything.
While the code is a slop hodgepodge, Haven is currently the only Discord clone I have found that makes it easy to selfhost; no extra open port except 443 80, single docker container, no extra database.

It looks promising, the UI looks much better. Other than the absence of a built in p2p livestream option, and an explicit no to federation.
