Thanks for all that info, looking into it all now.
Weakness i see is the print feature.
You can print to file, then OCR. But, is there any anit OCR techniques. One that springs to mind is to put loads of small, faded text in the background as such to trick the OCR and causing issues.
Bottom line is, if they really want it, they'll type it out, but its all about adding some barriers to deter the 90% of people.
Some people just cant be stopped.
