Ubuntu, Kubuntu, Xubuntu Finally. Finally the leader of a major distribution who has the guts to stand up and say what a lot of people have known for a long time, but didn't dare to say because it usually leads to a storm of criticism. Mark Shuttleworth has announced that Ubuntu will be moving away from X.org, opting to go with Wayland instead.

The main issue with X11's network transparency is roundtrip processing. In a remote X11 session, tons of stuff is sent back-and-forth across the connection. The worst of it in my own experience is mouse movement-- all mouse positioning is sent to the system running the X11 client app, which is murder when you're running a remote app over anything further away than your garden variety LAN. I've learned that ANY mouse movement is excessive and incredibly frustrating if you're working on a GUI on a system more than a timezone away or over any wireless connection.

Don't get me wrong, I love X11's networkability and have been using it to do remote-GUI and LTSP for a while now, but it is really an outdated model in these days of WAN/MAN/wireless connections to remote systems with more than 20ms latency.

Things are changing though, particularly NX/NoMachine, which I see as a wonderful and updated solution to the problem that (mostly) intelligently caches data between the connection. VNC and RDP are also more-modern solutions to the same problem (although they aren't root-less like X11's native support is). NX seems to be the path forward IMO as it works to solve the roundtrip delay problem inherent in X11.

My personal leanings would be to push for Wayland for local graphics, run a rootless X11 server on top and use NX for remote-GUI applications. I've already switched all my remote-GUI stuff over to NX anyway (if you haven't tried it, the difference is simply AMAZING for long-distance work) so the rest sounds rather trivial once Wayland is up to par.
