Hi there, I recently purchased a 15" MBP, and thought it'd be fun to put my old 12" powerbook g4 to work for me. Specifically, what I'm aiming to accomplish is to store my itunes music library (+130gb) on an external firewire drive that's connected to the powerbook. I'd like to be able to access and alter/update this library, as well as sync my ipod and iphone to it on the MBP, but I'd also like these changes to appear in itunes on the powerbook. Both machines are connected to the same wifi network, sadly ethernet is not an option here. How can I make this work? I know you guys know. Please help!
