Im not sure about the sky connection, but it is possible to run 2 computers through one BT line. To go wireless on the internet, you will need a little box that plugs into your landline that gives off signals for internet use, Not quite sure what their called but you can get them from PC World, Then to pick up the internet signals from your little box thing (If your computer hasn't already got built-in wirless internet connection) you will need to get a little thing that looks like a pen-drive that you plug into your USB socket, and that picks up the signal from the box. (Unless they come with the intrenet signal box) x
