There is obvious hack value in this, which I appreciate, but here's a solution for those with a more practical mindset and less time: a Fujitsu ScanSnap connected to a computer running Dropbox. I've been using this setup for years now and I can't image working without it. A single button press scans entire multi-page documents (both color&bw, and both sides of course) into PDFs which land in my Dropbox. I then use Yep to manage them.
