I think this about wayland vs X11, where the wayland protocol is local only and remote access generally involves sending pixels as opposed to draw commands around (which, unless you have a very good network connection, is usually the better option anyway, pretty much every time I tried to use X11 over the network it was unusably slow. Wayland also doesn't exclude being able to have remote windows as opposed to a whole remote desktop using pixel-slinging, but I don't know if any actual implementations support that).
So, will Linux follow Microsoft and move to something else ? That seems to be what the Linux Foundation is good for.
