Nice to see someone else has an interest in seeing multitouch supported.

I submitted a proposal for it to the improve-list a couple weeks ago.

It may also be worth considering adding new trackpad event types now 
that the world has almost universally moved beyond simple point-and-click.

For example, the OS X API there supports the following gestures:

- Pinching movements (in or out) are gestures meaning zoom out
   or zoom in (also called magnification).
- Two fingers moving in opposite semicircles is a gesture
   meaning rotate.
- Three fingers brushing across the trackpad surface in a
   common direction is a swipe gesture.
- Two fingers moving vertically or horizontally is a scroll gesture.

Their API gives provides these constant names for gestures:

- NSEventTypeGesture
- NSEventTypeMagnify
- NSEventTypeSwipe
- NSEventTypeRotate
- NSEventTypeBeginGesture
- NSEventTypeEndGesture

HC's mouseDown and mouseUp were great and still are, but the modern 
world is increasingly driven by a wider range of gestures.

How cool would it be to be able to write stuff like:

on touchRotate pDegrees
   rotate the target pDegrees
end touchRotate

...or:

on touchMagnify pPercent
   scale the target by pPercent
end touchMagnify
