KRUU - 100% Open Source Radio Station

I work for Richmond's public radio, WECI ( http://www.weciradio.org ), and was poking around for some open solutions to our technology needs. I found out about KRUU, a radio station in Fairfield, Iowa that runs completely open source. I'm hoping to use them as a model for how to plan some initiatives at WECI. Check out http://kruufm.com/ . Here's a wonderful write up on it on Open and Shut: http://poynder.blogspot.com/2007/01/open-radio.html .
