OSX multitouch Events with optical touch screen

Hi!
I was wondering if anyone on this forum has any experience with OSX multi-touch events and processing.
I have this optical touch screen that has some quite obscure but functional drivers for osx. It allows me to
drag and click (of course) but also to use the pinch gesture. I can pinch on the desktop and the icons all respond by resizing.
Now I tried two approaches to get this pinch functionality into processing; both failed...
1. a touchpad library:
http://www.steike.com/code/multitouch/
This works with the touchpad, but fails to recognize the touch events from the optical touchscreens drivers
2. using tongseng (converts touchpad to tuio events) to capture touchevents and a tuio library to receive them in processing.
The problem seems to be that both the multi-touch library and tongseng capture something more high level than the osx touch events that my touch screen driver produces (they register individual fingers for example).
Since I can actually see multi-touch working (resizing icons on the desktop), I can't help thinking it must be possible to get it into processing.
If anyone could point me in the right direction, or just tell me it can't be done ( preferably not), it would be much appreciated.
Thanks!
