Shoutcast is a popular streaming audio server protocol. NodeJS lends itself very nicely to doing this kind of thing so building an app around it makes sense.
Whatever is worse than alpha, this is it. Don't use it yet unless you want to help dev it. :) In that case, use it and submit patches. Thanks.
From the CLI
node shoutcast.js [mp3 directory]
From Code
var cast = require('shoutcast');
var station = cast.Station(conf);
http.createServer(function (req, res) {
first.connect(res, function() {
console.log("Stream ended?");
});
}).listen(7000);
station.start();
