Set up Hamachi ( http://www.hamachi.cc ) on both computers, create a network on one computer and add your other computer to the created network, open iTunes on the computer that has your music and make sure sharing is on. Go on your remote computer, open iTunes, and the shared music from the other computer should show up. This is an almost-no-setup-needed VPN. No ports have to be opened since it is UDP-based. I use it on all of my computers. When I'm at school and need to access one of my other computers, I just put in the Hamachi IP address of the computer I want to access and it works!!
