I am moving into a college house with a couple friends next year, and am trying to find a way to keep my macbook in my room and broadcast the music to a receiver in another room of the house. I have an external hard drive with about 60 GB of music. I would preferably have it be wireless so that doesn't add to the clutter of the house. The liability of leaving my laptop/music files out where anyone can change the selection (and more importantly, walk off with it) is too much for me. So long story short, I want to transmit mp3 from my laptop to a receiver hooked up to a speaker system. I imagine its a two piece system, but i haven't really found anything to stands out at me. Thanks!
