But only does mp3 streams.

You can find it for most platforms (Win, MacOSX, Linux)

The other tactic (such as for Real, WMA or QuickTime streams) would be to use an audio capture program (such as Audio Hijack on the Mac) to record all the audio the listening program generates. I use this method with a screen-movie-grabber (Snapz Pro X) to grab CSPAN footage and WH press conferences sometimes.
