Spot on. For larger rooms we will probably have to add mixing on the server side and that will definitely put more load on the server.

We also want to make it super simple to spin up your own Jam for example if you are organizing a micro conference over a weekend and for that we will need to better understand what that means so we can recommend what kind of server/specs to go for.

Thanks a lot for bringing this question up. We need a good answer.

We are currently reaching out to friends and strangers who have a bit more experience running high demand WebRTC + mixing setups to learn about the scaling challenges.

That said, we are quite surprised how well p2p WebRTC works for audio-only in smaller rooms if most participants have a decent internet connection.

WebRTC + Opus is magic.
