But you can do that from earth, you don't need anything in space. > Analogous to finding an eavesdropping device in your office. > Much better to feed it false information than shut it off.

I'd be interested in a reference for that one. China's theft of a crypto device is well publicized, so tapping is straight forward. Not sure they can fake a download, but I guess if I owned a satellite I'd be worried about the possiblity. On another note, since the satellite data is digital, you'd want several competing companies to feed you pictures. Otherwise simple faking is too easy. So it's in everyone's interest to have multiple birds all looking from different angles. Rather than fighting each other by getting in each other's way, they'd want to work together to ensure *real* pictures are available to everyone. Only governments would want to destroy birds, and they'd have a hard time justifying it (unless they were at war with corporations, and unlikely scenario in todays facist world). Patience, persistence, truth, Dr. mike
