 Bitcoin arbitrage is going to annihilate any false exchange rates between currencies over time

 I'd love it if someone put together a tool to see a Bitcoin inferred exchange rate & then the official exchange rate.

The divergence from official rates would be fascinating to watch.

 I imagine that information would be quite profitable to have. If someone took the time to record street value exchange I bet they'd be the ones benefitting from it and wouldn't want to tell the world. 

In Argentina for example, if you take the bank exchange rate it's much higher than the street rate.
