Electronic Ink Signature Touchscreen

I am trying to get an electronic signature on a touchscreen device, where a client can click a button, a screen will pop up for their signature, and then they will sign with their touchscreen, and the image of the signature will be saved onto the notes document.

Any ideas?

Thanks!

EDIT: I need a way built into notes, without XPages

Subject: Suggestion

I take it the to the pc the device appears like a input device just like a keyboard. Did they suppy some drivers and sample code for a .net program?
