Meh. As far as I'm concerned, Wayland is strictly inferior to X, so long as it fails to support network transparency / remoting. Talk to me when they have a real solution for this, besides VNC or supporting RDP.
Remoting will be up to the compositor implementation, it's not specified in the Wayland protocol. For example, Weston has just added a "remoting" plugin last month. https://www.phoronix.com/scan.php?page=news_item&px=Weston-6... This also allows for some really crazy ideas like a Wayland compositor running in a browser for remote app access. https://github.com/udevbe/greenfield
