Compositor/Window Manager for Multitouch

[Josh Leverette]

After you get started, let me know of any bitesize fixes I can work on. I've never worked on a large project, so starting small for me would be best, but I am very confident in C++. The main recommendation I have is to start from the assumption that this screen will be projector size and could be being used by multiple people independently, it would be simple to define the work area as being for one person if this weren't the case, but expanding it later would be tougher that starting that way I would think. Then it also makes you realize that either they should be able to tap on a blank piece of workspace or do something like a five finger touch to bring up an application launcher and window manager menu. The menu uses on Tiny Core Linux is very close to ideal, just a little dated in graphics.

This is my long term advice, but do whatever you are capable of doing.

I very much like the approach Wayland is taking, so I'd like your input on whether it would be possible to build this on Wayland.

There are some old discussions regarding TUIO (on X via evdev), but nothing recent. Does anybody know if Wayland is capable of handling such input? If not, would it be possible to extend it to do so, or is this something that must be done at kernel level (probably not something I'd want to mess with...)?
