Would tiling the bottom of the shuttle with iPads have been less expensive? Perhaps this technology would have kept those beautiful birds in service.

The alleged utility in verifying crowd-sourced images is a distraction, piggybacking on the occupy wall street thing, from this obvious commercial reality. Microsoft and Technicolor do not give a damn about keeping riot police honest by verifying cell phone pictures. They want to automate the otherwise expensive process of assessing fair use.
You should still do that experiment double-blind. Otherwise you're just playing into the unscientific thinking.
Trying to "double-blind" a comparison of the ones and zeros on either end of the cable may sound extra scientific, but in the real world it has no meaning or utility. This is to science as cargo cultists with halved-coconuts over their ears are to air freight. You have successfully identified a genuine component of science; double-blindness is very important in any situation where the experimenter can plausibly influence the results (such as with subconscious social cues) but you're applying it in a totally meaningless fashion. The experimenter in this case is not going to have any more influence on the ones and zeros under investigation than a coconut headset would have on the planes bringing holy cargo.
If the experimenter were trying to make a subjective judgment about audio quality, you'd want them to not know which cable they're testing (blinding) and you'd want anyone who comes into contact with them to be similarly ignorant (double-blinding). But since this is a comparison of raw data we're talking about the experimenters' knowledge is totally irrelevant - except to people whose only understanding of blinding is that it is "more scientific."
