I spent a lot of time overseas. My PC friends watch Netflix using a program called Anchorfree. It hides all your addresses so netflix doesn't know your overseas, and you can watch your movie.
Anchorfree is a VPN-tunnel. Just google it, download and install on a PC.
I assume you won't find anchorfree on iPad. But try checking out if there is a VPN app.
Or, as I can remember, you can set up a VPN connection directly in iPads settings.
But you definitely need an US-IP-address to be able to stream US content. (at least from my knowledge)
It's working ok, but at times it can be rather slow, so video streaming doesn't work that well (remember, it's a free service). And I think there was a time or volume restriction, too.
