A long time ago I had a chat with hacker about IP over short wave radio with PGP encryption... his hypotheses was one could do encrypted long range communication via IP that could never be stopped and would be tough to decrypt. Does such a system exist today?

You probably could do that, but then hiding the equipment required is a major challenge and in places like China will come with stiff penalties.
