Martian SlingShot makes the process of keeping files and now iTunes Playlists in sync between two or more Macintoshes as simple as a few clicks. By incorporating Apple's "Bonjour" technology, SlingShot makes finding and connecting to other computers on a network easy. It's the easiest way to keep your music -- including the expensive songs you've bought from the iTunes Music Store -- backed up and available on all of your computers. With SlingShot 2.0, you can Publish an iTunes Playlist of music onto the network and then Subscribe to the Playlist from other computers.
