May I humbly suggest that it is completely and utterly impossible to prevent abuse of this software? If you lock down your software and prevent people from using it the way they want, they will simply copy your techniques and build their own software. It may take awhile longer, but uncontrolled software will appear in places like China or the Ukraine or some computer shop in Pakistan, sure as the sun rises. The genie is already out of the bottle, and people are going to do what people do.
All the moral hand wringing out there is getting tiresome. Just throw in some checks against super easy bad behavior so the busybodies can’t say you didn’t try and get on with development without crippling your software. If your safeguards are too restrictive, competitors WILL release software that has no restrictions, and those competitors will prevail.
The consequence of this technology is that we’ll be unable to trust any visual or audio recordings in a court of law or public opinion. You’ll only be able to believe it if you see it with your own eyes or accept the testimony of a reliable witness. That future isn’t here yet, but it is inevitable. Better get used to it.
