Linux

If I had a nickel for every time someone ignored me just to say something I directly address...

You are pretty blatantly referencing X11 Forwarding / Network Transparency.

I can't reasonably assume you actually read anything I say, but to briefly reiterate:

Checkout Waypipe. Here's a direct quote from the README:

Waypipe is a proxy for Wayland clients. It forwards Wayland messages and serializes changes to shared memory buffers over a single socket. This makes application forwarding similar to ssh -X feasible.

Have you tried this? What is disatisfactory about it? And if all else fails, is there really ANY problem with simply using VNC/etc? What real-world problem do you have that is uniquely solved with this?
