Because, unfortunately, that's a whole new animal to deal with vs. wireless internet.
You'd have to find a "WiDi" receiver for your home theater system, (I doubt your computers have WiDi capability) and so you'd then have to get WiDi adapters for all your laptops. Even then, you still have to have a "clear" signal to the receiver (literally zero obstructions between the transmitter and the receiver). My WiDi goes out when somebody walks in front of the TV
But, hey, to each their own.
I have no clue on german online tech retailers, maybe you can pick one up by a Saturn
(they still exist, right? lol@"ich bin doch nicht blöd!")
