oh cool thanks, so as soon as someone starts broadcasting it will stop relayig and as soon as they stop it will start relaying again? thats what i need, and yes, i do have permission.
RelayServer: [Optional] If defined, the SHOUTcast server will not accept source connections, and instead attempt to connect to the server name defined here for transmission
Thats from the shoutcast ducumentation...
I want it to only relay when no-one is broadcasting.
