From another thread - http://bitcointalk.org/index.php?topic=5368.0
One solution would be to trade with family (or other trusted parties) in other countries.
Trusted traders well maintain accounts with their partners in other countries, going in debt or credit with each other.
Only once they have become significantly unbalanced will the traders settle their accounts.
Settling the accounts could involve sending the funds to a relative of the trader in each country, or any other way that minimises international money transfers.
We need a professional trade association with membership fees from participating merchants and exchanges which allow it to be managed.
A similar idea to the way visa is setup would work well.
So how do we start such a trade association ?
