Does anyone know if windows supports HFS yet? If it does just boot your mac as a firewire drive and hook it up to your PC.
You boot a mac as a firewire drive by holding down t when it starts.
No, Windows can see Fat, Fat32, and NTFS.
In this situation, a Mac with OS X can now see windows local networks. If they are both on the same network, use your mac to browse for servers (Go/Connect to Server...). Make sure your Windows File Sharing is checked the System Preferences and a user is setup on your Windows Machine, can be your regualr user too. Turn Sharing on for your iTunes folder in the Properties window. Then it's just a matter of transfering them into your new iTunes library.
