This is such a joke. In 2000, at the rump session of the International Conference on Financial Cryptography (FC00 to its friends), Paul Harrison and I got up after a few beers and had a Letterman-esque "Break this Mickey Mouse Projector Protocol" contest about an encrypted-to-the-projector movie-distribution scheme proffered by a, heh, entertainment conglomerate, earlier that year. The protocol was this belt-and-suspenders monstrosity, encrypted seven ways to Sunday, practically collapsing into a singularity of its utter "provably secure" canonicity. The winner, of course, was a simple question: "And, *where*, exactly, do we put the CCD?". Meaning that if *any* part of the scheme involves photons going through the air to someone's eyes, you can replace the eyeballs with a camera, and ... heh ... Walt's your uncle.
