I am very much rooting for Wayland. It is going to bring features like screen/tmux to graphical programs. Nothing like going to work at home mid day and attaching to the individual programs that you had running on your other machine. This is the reason I currently use terminal programs instead of X ones. Doesn't sound like Mir is providing more over Wayland than just including input, which arguably could be provided outside of the server itself.
Wayland probably isn't going to provide remote display capability, let alone anything like that.
All Wayland really does is hand out framebuffers in local RAM. The Wayland devs consider app display remoting to be a special case used by relatively few users, and outside the scope of the core project.
Yeah, and the nice thing about Wayland barely doing anything is that almost all issues are someone else's problem. The rendering libraries the Wayland developers suggest applications used are totally broken? Not part of Wayland, stop blaming them. XWayland is in a completely unusable state? Not part of Wayland, stop spreading FUD. I remember both of these actually happening.
I do not believe that Wayland would provide this functionality, rather that it would provide separation to enable this functionality. This functionality would be implemented in a compositor for Wayland. There is something similar for X, called Xpra. They list porting to Wayland as one of their "project ideas."
