Been trying to figure out a user friendly alternative that I can get my less technical friends to transition to. We all use Signal already for messaging but it just doesn't fulfill our screenshare needs.

Most important feature it needs is the ability to screenshare with system audio, such as for streaming games or watching videos.

I'd ideally also like it to be E2EE just for the sake of privacy and security.

From what I've read and looked into it seems the closest thing that meets my needs would be Teamspeak 6 as you can host it yourself, and with the new update it now allows screenshare with audio (either as P2P or via server).

As far as I can tell chat messages don't persist by default but it can be enabled (and this would be a feature my friends would really want too).

I currently have a Raspberry Pi 3 B+ but I'm aware it's a bit old and is ARM so I'm thinking of buying a Pi 5.

Do you think I'm on the right track here or are there any other options this community would recommend?
