FOSDEM: The Wayland display server

I'm not seeing where in the architecture Wayland supports cut and paste between local applications (or, in general, any sort of interaction between clients). So remote applications won't be second-class citizens in that sense, because it isn't supported at all. I suspect that there will be some mechanism outside of Wayland for it, and it will hopefully be something ssh/sshd will quickly learn to proxy. And, for that matter, it would be great if that covered other inter-client communication that X doesn't presently carry, like opening URLs in your web browser and libnotify.
