My thought was that the input transformation needs to take raw mouse 
motion and convert it to a position in a specific window.  The obvious way 
is to pass the events from the X server to the compositing manager and 
then back to the X server.  A more efficient path would see the 
compositing manager receive the events directly and pass computed events 
to the X server.  So, some way of getting the input device event stream 
redirected to another application may in fact be necessary.

Have fun. Oh, Matthew Allum (or other handhelds.org hacker) should help
figure out how to do the configuration part -- that's needed for touch
screens.
