I also thought about it. So you want a TOR hidden service, where you can demand video on some GPS coordinates anonymously and pay with BTC?
Possible, but it would be limited for a region, where the aircraft sits.
How to find enough people, who invest in hardware to run a wide spread service?
If people can 3D-print these drones, equipped with solar cells and contribute them to the network, it could become a funny whack-a-mole scenario with LE actually gunning them down with no actual persons made responsible
