Probably you can't do this portably, and even less likely in Python. 
However, I am suspicious of your *wanting* to do this.

If you want it to happen for *your application* (which would be much 
less Evil), you can possibly turn on mouse tracking for your top level 
window(s) and use QApplication::setOverrideCursor to hide the cursor.

I'd do something like, on every mouse move, set a timer at e.g. 1s 
interval if not set already and reset a counter... then in timer, 
increment the counter to see if your 10s interval is elapsed, and if so, 
kill the timer so that you aren't wasting CPU when the machine is idle.
