Streaming satellite radio anywhere in your house

Jason Fried writes about using StarLightXM and and Airfoil to stream Sirius radio to AirPort Express speakers thoughout his house. This is interesting for me not just for the neat use of software but for the simple fact Sirius radio has an internet version. With the exception of CBC, I’ve never been big on radio, but living in a country which has absolutely no quality radio in English, or arguably in Mandarin, this might make for enjoyable background noise.
