There are many sites on the web these days that show a different face to you depending on where you are located around the world.
For example I'm in Australia and there are a number of US based sites I would like to see exactly as would someone living in the United States.
I've heard that most sites use your IP address to determine your country. If so this would appear to make defeating Geo-blocking very difficult.
One of the only options I can think of is using a third party website that you visit that is based in the country you are interested in. This site then serves a proxied view of the page. I don't know of any sites that do this though.
Any ideas / thoughts / links?
