Presumably if a wireless telephone extention were used to connect mirror to the main subscribers phone (or wired either way, depends on how close a neighbour) & sky dish etc were ready to roll at the neighbours using the mirrors box & card. Lastly Sky would presumably install the a mirror box at subscribers address. I don't see why you couldn't use the mirror box & card at the neighbours still connected to your phone. I'm sure it would work & Sky package for 1/2 price + £5 makes me wish I was your neighbour. I'm sure Sky & Bt would have something to say although I doubt they'd find out. It would have to be box & card as the card is tied to the box, & if you blagged Sky you'd changed the box it may raise suspicion.
