However, you can do what I did when I first tried it- run the built in server. If you just set it to use iTunes as the source, use the Built in server with default settings. In iTunes, open a playlist and turn the music on. In NiceCast, click the Start Broadcast button, and there you go.

Under the Share Tab of the Broadcast window, it will display a URL that you are broadcastig from (it will be a numerical URl followed by “/listen.pls”. All you need to to to test is to go to another computer, open iTunes, and select “Open Stream” from the Advance menu or equivalent steps in Windows Media Player, Open URL I think it is called), plug in this URL, and you should be hearing the audio.

I think the un registered version will broadcast for only 10 minutes.

The other not mentioned alternative is if you have accesss to an Apple Xserve, you can use the free QuickTime Broadcaster to route a stream (audio or vide) to thes erver and then out to the net. I briefly considered this approach, but was not excited about admin-ing yet another server, and the costs for our Limelight service (where I don;t have any server side duties) were comparable to having an Apple dedicated server.

I’ve got NiceCast (another great app from Rogue Amoeba) and am wondering a little about the broadcast end. Any chance of some more screenshots on this in a Part Deux?
