I just downloaded NetBalancer earlier today to see how much bandwidth bitcoin-qt is using and got an unexpected bonus from it.  In addition to shows how much bandwidth bitcoin-qt is using, it also shows what countries the people connected to you are located in.  Right now, I have eight connections, six from the United States and the other two are from Canada and the United Kingdom.  Earlier today, I tried this and those six connections were also located in the United States.  The difference then is that the other countries were Germany and Lithuania.  I briefly had a connection with someone in China too while composing this message.

Has anyone else tried this?  I'd be curious to hear what other people are seeing for their own bitcoin-qt connections.  Unfortunately, it looks like Netbalancer only works with Windows, but there might be another programs that work with other operating systems.
