You have a point there... :-D
But then again the "normal" normal users don't have anything worth blackmailing them about (holiday pictures?), so I guess the target of this system would be companies, which would (might (should)) keep a distracted eye on what's going on on their computer park.
I'm definitely not convinced that smuggling stuff using a carnival float is the optimal method. Somebody might notice it, and wonder what is is doing there, at this time of year.
