No (at least, everything so far indicates that Wayland will never be

waypipe for "ssh -X". For "exporting entire desktop" both KDE and GNOME 
should support desktop sharing in Wayland.

Desktop sharing is usually using RDP or VNC. You need to check your DE 
manuals what options they support. It is completely out of scope for 
Wayland.
