You do realize that Venezuela has widespread censorship laws in place, including the ability to shut-off communications (Internet, Phone, everything) on a moment's notice?

If you want to set up a carrier-pigeon based BTC system. Be my guest. It literally would take something on that level to defeat the censorship regime that Venezuela has placed on its people. I doubt that a "Bitcoin over IP over Carrier Pigeon" solution would work on a wide scale however, mostly because Pigeons die and it takes a lot of effort to train and feed those birds.
I mean, if the Pigeon that was carrying your transaction was eaten by a fox, what then? Its clearly not a good solution. It seems to me that it'd be basically impossible to figure out or verify the balance of a BTC wallet if you were waiting the several days it'd take for a pigeon to fly around.
Just publishing the current Black-Market exchange rate of USD <---> Venezuelan Bolivar is hard enough. I have my doubts that BTC would work under the censorship-heavy Venezuelan regime. And I have severe doubts that the crypto-libertarian dreamworld of BTC would ever become sanctioned by the current Venezuelan Government.
But that's my viewpoint as an outsider. I admit that I don't live in Venezuela, but it seems like they have a lot of problems and "Bitcoin over IP over Carrier Pidgeon" won't be able to solve.
