[linux-audio-user] synhronized play of single audio on multiple media clients

Hi, I'm more or less linux sound newbie. I'm using few popular open source projects (Misterhouse, Plutohome), that all implement some kind of multiple audio clients using Xine, Alsaplayer, VLC and media is stored on server. Now this scheme works quite good, the problem arises when one would like to play single audio on multiple media clients in synhronized manner, so one would not hear any differences between separate clients. Now I wonder what option I have to implement such system.... I'd prefer to use VLC, Xine or Alsaplayer as clients if it's possible to somehow synhronize them at server. Also I'm interested if I have any options to synhronize audio playin at client side.... If you would implement such system, how would you do it? With what tools (I'd prefer open source solutions) ? Also I'kindly ask if you can point me to more info about this problem Thanks in advance for your help, regards, Rob.
