Looking for local document OCR, tagging and filing. Somewhat like Evernote.
JayNeely: E-mail Evernote about it. Licensing their software to businesses who want similar functionality but complete privacy for their data could be a business opportunity for them, like the Google Search Appliance: http://www.google.com/enterprise/gsa/Offer to beta test for them.I don't know of any other companies that do have what you're looking for, but I would check Adobe & Xerox's offerings if you haven't already.
