Wayland is a compositor+window manager+display server AIO

Not in particular, however I believe there exists a demo toolkit. You're
supposed to use toolkits such as Gtk+ and Qt in order to display things.

I'm going to say no, but I don't know what uTouch supports.

Wayland can run on Wayland, X11, DRM, and in the future (now?):
framebuffers. So you can essentially nest it on anything you want,
including itself.

Neither of your projects will be portable to wayland in the way you're
hoping. You'd literally have to work them into a compositor. That is to
say that instead of touchegg communicating with the window system
(compositor), touchegg would have to be part of the window system
(compositor). The same goes for eggwm.

Hope that answers your questions.
