Totally agree - its an impressive piece of work and strongly recommend any one interested in this area to read the blog posts that were made during the project:

They are definitely worth going through and Manuel Stoeckl deserves a lot of good karma for taking this on.

I agree that it's impressive, but my biggest objection to Wayland is uuuh... that it doesn't work. This is honestly mostly NVidia's fault, but still. I have a laptop with dual Intel and NVidia graphics, and there is as far as I can tell no way to make Wayland understand that my external monitor is connected to the NVidia card. I tried both Nouveau and proprietary, but then I switched back to X11 and it worked instantly.
