I don't have any suggestions yet, but want to ask whether you want verification done by a human or by a combination of human and computer. (For example, _currently_ all video recordings produced by the AI would have mains hum mismatched with the time and place where they were supposedly recorded. Alas, one can't detect that by Mk. 1 eyeball.)
@robryk I like that idea - so yeah, we can both rely on our own computers to do analysis (but not, note, a 3rd party machine).
