I live in a house with around 30 people and we all have systems setup in our own rooms (computers to either computer or stereo speakers) so the synchronization (from what I understand) must go through the computers because not everyone has a stereo to pick up a FM signal unless you can do so through a computer. We want to play the same music somehow from one computer to play on all others, so that it plays throughout the whole house. Any FREE ideas? We all have iTunes by the way...
