So this seems useless for payment, but here is the real hidden interest:
You can send a file up to 10Kb, and pay for byte sent.
It's cheap, coast looks to be $0.0035 for a 5Kb file.
The receiver can get the file, encrypted, without internet, using only a SDR tv card, amplifier and antenna, worldwide, in 10 minutes.
I see there large possible applications!!!
