Until the NSA parks outside your house with a transmitter :-) How do you know it's really random?

  I bet if you wave your antenna around, pointing at some bright stars, while doing a few of your favorite dances, that ought to make that gathered data stream pretty hard to replicate.. As far as I understand, in terms of practicality, "randomness" isn't important, only obscurity and/or unpredictability.

  You could use a directional antenna, and point it straight up. I mean, sure, you could put a geostationary satellite or something above you, but that's just getting silly at that point.
