one of the projects I can think of is graphics tablet support in wayland.
This requires a whole bunch of changes in a couple of components:
- libinput needs to be modified to support tablets
- a wayland protocol needs to be designed to get that information to the
clients (I had a proposal last september, can be extended)
- the matching weston implementation
- client-side code to test this, including e.g. GTK

This is a rather big project, so it needs to be well scoped so you know what
you're getting yourself into :) There are a lot of oddities and quirks about
tablets at the moment.
