Ok, so you know how if you live in a certain country and you want to get something from the US (for example) and you can use a proxy to get what ever you want. Like my computing teacher uses a proxy so he can get Netflix on his PS3 since we don't have it in NZ.

My question is, can I use a proxy or something to play games with my friends from the US? I want to play L4D2 and some other games with some friends I've made that live in the states without having to deal with a 200+ping every game because of the different regions.
