I think it would be a great move for them, if they choose to. Since much of the worlds foods are grown in Latin America it would be in their best interest to export foods and ne paid with bitcoins. Not only would that help to spread the use of the btc but also create and grow a much needed industry if btc is to truly take hold.

If people can use bitcoins to buy everything needed to live, e.g. medicine, technology, food and clothing, people will be more inclined to make the switch from local government paper to global electronic currency.

just my 2cents :-)
