There's a new feature in Apple's iTunes 9 music software called Home Sharing that lets all the computers in your home easily transfer media back and forth. It's a great solution for those times when you buy an album or TV show on your computer, and your wife or child wants a copy on their computer as well.
The first step is to make sure all the computers in your home are running iTunes 9 or later and are connected to the web through your local wired or wireless router. Next, find the first computer you want to share from and select the Home Sharing icon in the left window of iTunes.
