[GTALUG] Music Broadcast Server?

I currently use Mediatomb as a server and have Panasonic UPnP players. They are mainly Bluray players but do more, including play .flac files. But they each connect separately and play their own streams independently. What I would like to do is have each unit play the same music stream. It would be like having multiple radios in my home set to the same station. Is there a Linux solution for this? Cheers -- Stephen
