I have a server where I keep all of my music. I share this server with my two roomates. I have a Macbook that I run iTunes on, and I have a PowerMac G5. I want to share iTunes with all four systems -- my two computers, and each of my roomates' computers. My two systems are Mac, theirs are Windows 2000/XP. Additionally, later there will be a fifth system added as a "media" system connected to our TV. This will probably run Vista or XP. Generally speaking, at least three systems will be in use at the same time. How can I setup iTunes' database so that it can be shared between all four systems? I want to be able to add a song on any computer and see it show up on all the others. Since they all share the same storage system, I wouldn't imagine this to be too big of a problem -- would it? I also want to do the same with Podcasts. Of course, since I'm really the only one who uses them I'd set the others to not update automatically so we don't get multiple copies of the same episodes downloading at the same time.
