I think they are different things. The current airbrush implementation is too 
simple-minded, but the spray paintop and a proper airbrush paintop are 
different things. But to develop a proper airbrush (with support for the wacom 
airbrush controls), you'd need to have some experience with a real airbrush.

The main difference with spray and airbrush is that while an airbrush sprays, 
too, it sprays particles that are generally too small to see :-)

And the other wacom airbrush controls. That's the way to go, I feel.

Well, I didn't copy the gimp code orignally, only made sure it kept depositing 
color when held stationary.

of course, what would be really cool to have with a proper airbrush 
implementation are two things:

 * drip (if you spray too long in one place, the ink should start dripping
 * a set of masks. If you use a real airbrush, you generally have a set of 
masks at hand that allow you to spray thin lines, shapes etc. I know you can 
achieve the same effect with the current selection/masking code, but it would 
be really nice if we had a drawer with predefined mask shapes that you could 
put on the canvas, move about, spray over and put back.
