Network Transparency with Wayland
On X11 you can design far more efficient remote apps via GLX serialization.
You could heave a headless server that has no graphics card render 3D applications on your local machine which might have really beefy graphics hardware.
Something that will never be possible on Wayland because its truly flawed protocol design.<p>This solution to "network transparency" is nothing else than pushing the whole screen updates directly over the wire. So why not use established protocols like VNC?
