We are not talking about DRM here. Let's not break the butterfly on the weel. People that don't understand what digital signing is are perhaps not the right users for DRM. Yes, DRM would be an option, but I doubt that it is what the OP was asking for in the first place. ;-) And IMHO DRM only works if you have full control over hardware and software. Of course circumventing protections applied by DRM is incredibly hard (even without the mentioned full control) compared to circumventing "protections" by simple flags or scrambling of content.
