This would be cool for noVNC. You could access a desktop from anywhere.

I have never been able to set up a reliable remote desktop connection to a Linux machine. I want a VNC on windows experience where I can control the other machine while that machine sees the same thing (e.g. PC plugged in to TV but I can control it from my laptop like I’m on the TV machine).

I eventually gave up because I couldn’t get something lime that set up.
