I was at the post office yesterday, and nearby there is a little shop that sells prepaid phone cards and money services, mostly to Mexican immigrants. I've bought phone cards there before, and went in to talk to the owner about buying bitcoins. I didn't offer any pitch, just mentioned the website and said that I'd be interested in buying from him if he offered them. He seemed intrigued, and was on the website before I left the shop. If there are going to be local businesses selling bitcoins for a decent markup, it's these businesses that profit by helping immigrants in America send money to families abroad.
I don't even know what these places are called.
Nice, but unless there are bitcoin exchangers in every country, such effort will probably have totally no effect.
People need to exchange bitcoins for their local currency and do it locally, otherwise bitcoin is muich worse than western union or moneygram in terms of money transfers worldwide.
