Actually, restricting purchasers of tools from doing what they feel 
appropriate may not be the best course of action.  I'd be in favor of 
providing a method for the right combination of tools to automatically and 
securely render content to "trusted technologies".

Hi;

Yes, Open Book and Kurzweil do allow you to print to a virtual printer
driver so that you may perform OCR on PDF documents.  However, the problem
with this approach in terms of the PDF digital rights management system, is
that a publisher can disable printing of that PDF document, rendering
conventional OCR useless.  I can think of a way to perform OCR, but it would
be restricted to the currently visible portion of the Window, and would be
CPU intensive, as it would work based on the GDI GetPixel() function.

So, the only way to guarantee accessibility to PDF documents, in my opinion,
is for the ability to turn off content extraction by access technology to be
taken out of Adobe's DRM system.  The other methods either have technical or
legal implications.
