Removing Ads from a Live Audio Stream in Unix?

Soothh writes "A local radio station here is finally doing streaming audio again on the net so i can listen at work. The catch, they go through Hiwire, which only supports Windows Media Player. Their tech page says that this technology has 'proven difficult to implement on the Unix platform.' Is there any validity to the claim that WMP is the only cost effective way to remove commercials. Anyone know other ways to get streams from real radio stations on a *nix platform?"
