+1 for the Squeezebox/music sync feature. This would be brilliant. I know there would be delay between two rooms, but would it not be possible to use a config menu to set a " +/- xx millisecond" delay on either the server or client in order to get the sync correct, and once set this wouldn't require adjustment. I have a server and two clients, (soon to be three clients) and it would come in handy when working around the house/ having a big party. Cheers, M.
