Just watched the video, it doesnt look like its low level driver support at all, they are using similar techniques to what im planning. They showed 2 applications that zoom using the scroll wheel, which they have simply mapped gestures to.
MTV will work in the same way and allow different mappings for each application, for example a 2 finger drag could send a scroll wheel event to the window for ie or send a shift+scroll event to 3ds max or whatever you need.
It also looks like they are just using the standard WM_INPUT system for the presses from the touch screen which is only a dual input screen. This system works just like having 2 mice attached when you are only pressing 1 thing it just moves the mouse there and sends a click, but when you are using 2 methods of input they assume its a gesture and apply panning/zooming. The last app they show is not a standard windows app and handles the WM_INPUT messages directly and draws them to the screen.
Our system will work in a similar fashion but will will also allow standard window rotation and scaling
