Yeah. It makes much more sense for his scanner to be attached to his laptop.

I share my scanner, but the host machine is running Linux and uses a piece of server software called SANE, and then someone wrote a TWAIN driver to attach to that. It works quite well.

On the other hand, if you don't have to log in to your desktop machine, Rev., then it would probably be easier to just share the folder you scan the pages to and then access it via normal Windows networking, as Tony suggested.
