Osculator is cool, but this looks like it has potential.
**Specifically I used it today to plug and play a wiimote as my system mouse.
It works well-ish, and is free, so it may open up so more avenues, since it
appears to work with any windows system… Really, Windows of all other
operating systems. It has a built in scripting function, so you can write
your own functions, or use a relatively unintuitive GUI to set gestures.
The documentation is awful, but complete, as a rtf file included with the
package. It looks like it was originally designed as a midi interface, that
has been expanded for other purposes, but I don't think that is much of a detraction.
I think the only problem is that it is very windows centric.
