I have a MacBook Pro, iMac G5, TV, and an Airport Extreme Base Station. I love the ability to stream my music from my MBP to the TV using airtunes.

Is there anyway I could get the same music to be played through the speakers that are hooked up to the iMac that is located in a different room?

It would be great if I could walk through nearly every room in the house and control the music through my iPhone and RemoteBuddy.
