Tablets :: Using Touchscreen As Touchpad?

current versions of Jump Desktop for iOS and xtralogic remote desktop for android is that they allow you to switch the touchscreen to touchpad mode, and then control the pointer with the screen like a touchpad instead of having to hit something with your fingertip. This great for when you need a precise pointer, or for controlling the cursor from a corner without having to release your grip on the device, but in addition to that, on Windows 8 I could also see potentially using this to control a second monitor (like a TV) with your touch monitor (say the newly announced wireless lenovo monitor connected to a windows 8 HTPC).

I don't have windows 8 yet, but I was wondering if there was any such utility for windows 8 currently or in development. If the thin and light wifi monitor idea takes off, it would be great for an HTPC - you could play video on the TV while browsing or such on the tablet, yet you would only have to have and use one computer.

For photographers and artists you could use the USB3 version of the display or small touch capable cintiq on your desk in front of you, pushing your keyboard and mouse out of the way, but with a quick mode switch you could still control your main monitor without shuffling things around (something I've found frustrating when switching between a traditional wacom tablet and keyboard - something is always out of easy reach). Of course that also assumes you could still bring up the on screen keyboard on the touch display.
