In University, I drilled a hole in my dorm closet wall to my neighbor's room so we could run a wire between our stereo systems and I could play whatever he was playing through my speakers. This is like that, for the digital-networked age.

I lived this. It was a great way for me and several of my closest friends to learn about the variable latency among devices between pushing the play/unpause button and when a cd track actually starts to play.
