iTunes Question

A Question for all you Mac/iTunes users: Is it possible to get iTunes to play music from across a network? I have a file server, upon which I store MP3 versions of many of my CDs. There’s far more music than there is space on the Mac. I’d like to simply play those files, through iTunes. I don’t want iTunes to download them to my mac, or anything like that, just play them. Can I fool the Mac into thinking that the network drive is local somehow? Of course, this file server is running Windows (XP Pro), so that may be an added wrinkle. But it would seem logical to me that Apple doesn’t expect people to keep their data locally in this networked age, and so I’m assuming I’m the one being a git, not Apple. But! Any instruction would be most appreciated, as a (admittedly brief) browse through the help didn’t reveal anything.
