Andromeda is a super easy way to get your iTunes streaming back. The functionality anyway.
OS X ships with everything you need to run Andromeda: Apache (or “Personal Web Sharing”) and PHP. You can even configure Andromeda to serve files downloaded from the iTunes Music Store (see bottom).
Remember, I would never encourage you to break the laws of your land. That’ll just get you in trouble. Or maybe me. Anyway, have fun streaming again.
What do you suggest for streaming from your OSX box?
