A video conferencing setup

Hi there,

I was wondering if anyone has built a video conferencing system on top of tailscale.

Something like the following:

Two raspberry pi’s installed in remote physical locations running tailscale. They are connected to TVs via hdmi and have webcams with microphones. The OSes start tailscale automatically and Xserver.

The owner of the tailscale network can at any point start the video conference. When that happens each pi sends the local webcam video feed (and audio) to the other endpoint.

Please share your thoughts, setups or links relevant for this project.
