This is a bit of a weird one but I have just bought my first laptop and I am making it my aim to make it need absolutely no wires other than the power: I have a wifi printer, bluetooth mouse, iPhone syncs wirelessly. But I can't get rid of the need to plug in external speakers. I really want to broadcast the exact output of my soundcard (without extra hardware connected wired to my laptop) to a fixed set of speakers. I know apple's airport does something like this but only through iTunes and it's really expensive. Any other ideaas?
