I got me a magic trackpad specifically because Apple's trackpads are so nice, and it allows me to pan/zoom large canvases in both dimensions (I've put it between the split halves of my keyboard, and sometimes use it with my left hand, while the right stays on the mouse). I've never considered panning/scrolling with one finger, it sounds very convenient. I guess this is something that could be hacked in software? Trackpads just send the coordinates of the touch points to the OS right?
