>Ham radio would go farther, but sending encrypted communications over ham radio is illegal, so that's right out. This is the next best thing.

How come? I don't know much about ham, but it doesn't seem like it'd make much sense to make it illegal.

Ham radio spectrum is strictly for non-commercial use. If encrypted communications were allowed, it would be a lot easier to sidestep that with plausible deniability.
