I wrote all of my views about exporting culture and stuff before actually reading your blog post. It's a very good post, and again, the situation in Mexico is similar. Lots of humble people are absolutely dependent on Western Union and get constantly ripped off, and again Bitcoin comes to save the day.

A factor to consider is how soon will bitcoin be illegalized. Bitcoin is clearly a threat to banks and money transfer services, so they will be lobbying hard against it. I'm sure it will be a different scenario if the exchanges start popping out now, while it's still legal, than if they do after BTC's illegalization. People might more easily switch to an illegal way to transfer money once they've felt the advantages of it, than try out for the first time an illegal thing (I'm sure there will also be fear mongering tactics by the media). So I'd say that anyone thinking about setting up an exchange, should be quick.
