Ok, I want to be able to have itunes on my laptop and my desktop and be able to sync any device on either of them. My music source is on a shared drive on the desktop and I already have itunes on it. I just want to be able to install itunes on the laptop and access the music from my shared drive whenever I am connected to my home network. From what I've read, it can't be done unless I physically swap a portable drive between them. Anyone have any experience in this area?
