xforward replacement by having waypipe support non wayland hosts.

[maiterth]

Hey,
this is something that I would love, like Xquartz and Xming but for wayland (servers) on different platforms hosts.
At the same time I know this may be a large ask for someone not knowing what the implications are.

When running on clusters and attending trainings (HPC performance tools, etc.), I often see as the first task saying 'install xming or xquartz to be able to run with GUI software from the server'. It would be very nice to allow this kind of software to not rely on X11. :)
