Automatically Sync Your iTunes Music Across Several Computers with Syncopation

I’ve been struggling to figure out an efficient way to share music with other people in my household for a while now. Until now my solution has been to copy files on to Time Capsule so that other family members can pull off files in to iTunes from Time Capsule’s shared drive. However this requires manual actions, and it also means that we’re pretty dependent on Time Capsule. Fortunately there is another resolution out there to keep your itunes library synced amongst two or more computers, and this one seems more efficient. Syncopation by Sonzea is an app for Mac which once installed on two computers, it will find music on both macs and automatically transfer the music files in between them so that both computers have the same complete music collection. Whenever you make changes to your music library, iTunes will automatically update all the computers over an Ethernet or wireless network. Syncopation retails for $24.99, but you can also download a free 30 day trial. And sorry PC folks, this app is unfrtounately Mac only . Does anyone know of a comparable app for PC users?
