If you have Sky in your house then you can just use your username and password on xbox live and you can watch exactly the same channels from anywhere in the house but without having to pay any extra or fit another satellite box, wires/dish .
Far Far better than anything on any other console , worth the £22 yearly Xbox live gold sub for this alone.
so if i have sky and give my password and username away, all my friends owning a xbox360 + xbox live gold can watch sky for free???
dont be ridiculous.... it registers your console as the user.
thats why i said -impossible. :p
