Yea it does...but I need lower level mouse access. Windows and Linux support a single cursor design which means if a system has two mice they both control 1 cursor. Either mouse moving causes a mouse moved message in windows but theres no way to tell which one unless you have a low level hook.

*edit*Whoops...take that back, apparently the latest version of X server includes MPX which is pretty much what im looking for. Just gotta figure out how to get it working.

*Another Edit* Looks like theres going to be a wait:
