Great!

I'm afraid that I haven't put any real thought into Wayland; I did try
to construct it so that it could theoretically lend itself to other
display systems.

In theory, the bulk of the work should involve abstracting the
display.[ch] logic to have an xcb flavor, and a wayland flavor.

I do see that I used some xcb code for input related stuff in session.c;
that would probably need to be abstracted as well.

I also just pushed a batch of changes I'd been sitting on.  You probably
want to do a git pull before you start any work.

Cheers,

Jeremy
