Electronic Signature in Flex Mobile Application

The current mobile application I am developing in Flex calls for a client to be able to electronic sign a signature box in a document with their finger (This is a tablet application). Does anyone know of a good way to accomplish this in a Flex Mobile Application?

Thanks in advance for any adv开发者_运维问答ice!

I saw this post and that no one had answered it yet, so I'm taking it by storm. Here is a scribbling/signature example I cooked up for you. It's written with Flash, but the as3 will work in Flex just the same. I didn't have "Flash Builder" installed on my home computer or I would have done this in Flex (sad face).
