The feature in question would allow you to connect directly to a player without an actual actual server, is it already possible?

To do this, we will need to host and stream the audio on our servers, which is currently not possible. This is not included in our "immediate plans", but I don't deny that at some point it can be added

but can't you add something like a connect to it thing? so at least a user could have the server running on its minecraft (or externally) and you could connect to the person's ip

(webrtc is a thing too (serverless), idk if it would work in this case though)

Normal infrastructure

WebRTC

Probably won't work on this, but will leave the issue here as an idea
