iCommune: the iTunes plugin I've been waiting for all my life. Now, all it needs to do is collaboratively filter my playlists and iTunes ratings with the pals on my network.

iCommune is a plug-in which extends Apple's iTunes software to share music over the network. Your friends' music libraries appear in the iTunes source list. You can browse their collections, and choose to download or stream their music. It also allows you to make your own music library available to others.
