Phoronix was at the Linux Foundation Collaboration Summit and has two articles on the status of Wayland and X11 integration. The second talk was about the current status of Wayland, and its impending release (version 1.0 is due this summer). The developers also have an experimental GNOME-Shell working on Wayland. There's a (kind of shaky) video of this talk (attached, and at youtube for those wanting the html5 version). The first talk (by Keith Packard) covered X11 support on Wayland. It's basically ready to go, but window management is implemented only as a hack right now. The next year could be quite exciting for GNU/Linux and BSD users as distributions begin including Wayland as an alternative to X.org.
