I've been meaning to ask: is there a reason why you don't just use a VPN service like
IPVanish or
Private Internet Access? These services offer just what you're looking for, without too much trouble. Cost isn't that bad either. Starting at about the cost of a Raspberry Pi per year. I've been using IPVanish to watch the US Netflix, and this has worked excellently for me. If you combine it with a DD-WRT or Tomato router, you can have it always route your traffic via the VPN service, effectively offering your favorite streaming service to any device connected to the router.
