Mac OS X's application "Preview" lets you sign a blank piece of paper, take a photo of it using the camera, and shove it into a document.
You can also do this for multiple signatures, and/or save signatures.
Tools -> Annotate -> Signature
EDIT:
Technically, a digital hand-written signature is not a valid signature because it's, well, digital. It can be copied over and over again. This may be your point for using one, but having a digital copy of your signature defeats the entire purpose of having a signature in the first place.
I suggest you convince them to let you sign everything you get in PGP/GPG. :P
Sure, you can scold me on the fact that the private key can be stolen as well, but at least the key is password protected, while your signature on your hard-drive is probably not password protected. And your computer password does not count (unless your entire hard-drive is encrypted, in which case it counts, and you're safe).
