If they could be required to use a publicly known format for their transmissions, with no restrictions on reception of said signals for any purpose, them I'm all for it. Having some known fixed beacons spewing transmissions that could be received and then used to recover the source information before encoding, would turn all of the transmitters into a wide-band source of probes for the ionosphere that we could all benefit from. Knowing the format of the transmissions would also allow us to develop SDR software that automatically filters it out, completely. This would also allow us to use the same transmissions for passive radar, as all the transmission sites are fixed. This could be a win-win for everyone, as long as the format is fixed, and publicly known. What they do with the data before sending it into the ether is their own business, I'm sure they could generate sufficient amounts of truly random bits and courier it between locations to use one time codes (a simple XOR, with almost ZERO delay) to keep their confidential business information safe. 20 Kw might seem like a lot, but the ionosphere is a fickle beast, and this isn't going to be completely reliable even at those power levels. It's only about 13 dB more than the most powerful ham rigs, and 3 dB less than most Clear Channel AM radio transmitters. It's not entirely unreasonable.
