but your mission does not make sense to me. If you are running a MD that means your core is up too. If the core/MD is the same machine, then ideally your media should be on it. why would you run two or three machines to listen to music?
Or am I missing something here?
If it is other way , i.e. you are trying to stream music from your core to any pc in the home.. should make more sense. A possible solution is, Lmce by default hosts mediatomb upnp server (not fully functional though) that will allow your media play on any machine.
once again, sorry for the comment but educate me !
