I think, if you are against a powerful opponent, it would need something like controlling the hardware infrastructure..

One idea that is organic and can work with simple Wifi routers is something like mesh networks.. so the people with wifi routers next to limits of a free neighbor country would have access to routers with internet..

Of course, to build such a network, some sort of incentive are needed.. maybe creating some sort of bitcoin for mesh networks would do it?

This would also help in war times.. anyway.. at least you are giving something back, a starting point.. maybe this will end in a org for you.. and you will have the means to achieve more?

Congrats for the attitude.. it may mean a lot for people who really need it
