SuperSync 2.2 is now available. It's music library synchronization software. SuperSync costs $29 for a two-machine license.
SuperSync enables Mac and PC users to synchronize their personal music collections over a network. Any two music libraries can be compared and merged, with new files added automatically.
The 2.2 version adds iPod importing capability, to allow users to retrieve songs and playlists from their iPods. It also fixes a small number of bugs that were in the previous release, including a "help" bug that affected Leopard users. It's a free update for registered users.
System requirements call for Mac OS X v10.2.8 or later.
