Ipad as a graphics (Wacom-like) Tablet.?

Hi, does any one know if there is any thing that could make a ipad into a graphics input device like the Wacom tablet..??

wacom make a LCD tablet input device that is staggeringly expensive in Australia.

I though such a use would be great for an Ipad.

I own the wacom tablet. Don't ever use it

But I doubt you could do it with all the security restrictions. You can always find an app to draw on the ipad, but I doubt you can get it to track a pen tablet and get it to input into the computer.

There are apps to turn the iPad into a giant trackpad, and if you got a stylus for it, you might be able to do it. Not sure how well it'd compare to a Wacom though.
