I go to Australia fairly often and know quite a few people who live between the US and AU. Finally frustrated beyond the breaking point by iTunes and Netflix goe-location nonsense, I got one of these small servers(1).
I loaded openvpn(2) server on it and put tunnelblick(3) on all our macs (and a few openwrt type devices)
Cost of a tiny dedicated Atom server payable with paypal: $39/month. Having an IP address that that says I'm in New Jersey wherever in the world I happen to be: priceless.
