I want to give a house-warming party with my friends. During that party we want to play synchronized music in all rooms. We thought we could realize this by setting up a shoutcast server. Every pc in the local area network logs in to the stream from the central server, everybody connects their pc to an amplifier and off we go!

But now I've done the above but apparently every stream has a certain amount of delay compared to the server. This varies from 2 secs to almost 30 secs... Anybody any idea how we can overcome this problem?
