If I were to live in a city where wireless internet spanned acrossed the city, I would want my car radio to listen into my shoutcast broadcast of my mp3 playlist at home, as well as all of my friends playlists. It could play the local mp3s on the cars hard drive as well as any music CD or CD with mp3s on it. In addition, it would have a FM tuner to listen to normal broadcast. Ideally, if when I'm listening to a shoutcast broadcast, and the signal weakens, it could automatically search on the local hard drive for that song and start playing where the shoutcast version left off. I want to be able to pull up to my house, and without getting out, pull mp3s off my house's computer network and put them on the cars local hardrive. Say you are looking for a new song, while you are sitting in traffic, you search the public repositories of the cars next to you in neihboring lanes. This would be done automatically so you woudln't have to fiddle with an interface at every intersection. I want to control the system with my cell phone too.
