I just realized: my postings were answering the questions just as little!
So I take it back...and the attitude too.
But despite the poor reason why fastfiat needs to hide his IP, I thought it would be interesting if it is generally possible. Changing IP could work like a proxy so the website or app assumes I'm in a different country, right? On my PC I have to use something like that to be able to use hulu or the bbc iplayer.
