Wayland won't feature remote windowing. The best we can hope for is a pixel-scraper which dumps compressed bitmaps over the network.
You people need to get over your whole "x11 can run over the network" thing... I don't care what the theory is, nothing beats RDP (windows remote desktop) for running applications. I've used them all: rdp, vnc, ssh -X, nx... nothing comes close to rdp, and if you guys took of the "windows sucks" blinders you would admit that too. Whatever advantages Xorg might have, running appliations remotely is absolutely NOT one of them.
