Good comment and largely I agree. Bundling a powerline solution with the box (as BT Vision does) would be the best solution and much more reliable than WiFi. That's how I have my Smart TV set-up and it works well. However, one extra consideration is the rising number of '2nd screen' apps. E.g. apps that let you control your TV from your mobile/tablet or Zeebox type apps that adds services based on what you're viewing. I can see this sort of solution being really important in future (even is YouView was not initially designed to support such things). Whilst having powerline for your YouView box should not rule this out if there is WiFi on the same network in the same room, it does add a layer of complexity.
