Is there a PPA with a Wayland build I can use?

I do not think there is a ppa at this point. It would also not be very beneficial right now. What I gather from the information, I have seen so far, wayland does not yet have enough feature implemented that it could be just plugged into an Ubuntu or Kubuntu Desktop.

Hence, currently it is more something for developers to test out, who probably have no problems to just build the tarball, or clone a branch directly from the git repository.

I just found this: https://launchpad.net/~xorg-edgers/+archive/ppa Anyway, don't know how to use it =P

This might be the closest you're gonna get. Again, sounds like its not currently far enough to be useful to build.
