I use Tracktor Scratch Pro with a macbook pro. what else do I need to stream with? I use to use winamp/shoutcast but its windows only

you can use Nicecast there is a pretty good thread in here some where about it. You can also use tractor its self just go to broadcasting in the preferences.

here is the link to the Nicecast set up.
