Corey, I have one off the wall approach that may or may not work for you. If you convert your scanned images to PDF then use something like Acrobat to convert those PDFs into PDFs with hidden text (The OCR data). You can then tell Acrobat Reader via XML what to highlight when your user opens the PDF. Not sure if that helps you but may give you some alternate ideas.
