Signature Capture app?

So, i had an interview this morning for a job, and have an opportunity to earna great deal of brownie points with the business owners!
They were thinking of purchasing some sort of electronic signature capture device (like fedex or UPS has when you sign for a package) for invoices.. BUT.. I also mentioned my Droid Eris and how it can do so much... Turns out, both of the Owners have DROIDs lol..

Anyways.. I want to know if anyone has seen some sort of application that can capture signatures, and either save an image to be emailed, or email directly from the app..

OR does anyone know a DEV that could create something as simple as this, that I can talk to and relay updates on the APP to the owners of this company..

They seemed really interested in it, and I'm pretty positive it will show a good bit of initiative in saving their company money from the get-go (on my part)

It would be AWESOME to maybe have a custom app built, specifically for their company, but anything at this point (instant gratification method) would help!

Yeah i noticed, the signature thing may be funky because of the Stylus issue, but finger signing is going to be the way of the future LMAO.. I've played around with "Draw and Share" in the market.. which could theoretically work, but it's not as specialized for the use I will need it for.. Too many extra features for something I will be using in a professional enviroment.
Draw and share has lots of colors, and clip art you can add.

LOL thanks man! I appreciate it!
