I checked the URL to see who is hosting the audio feed, and the link goes to:
this site at rbn.com, RealNetwork's site for managed content hosting. So... If Real can't reliably stream high-demand content over the Internet using their player, what chance do we have?
Hm... I wonder whether a streaming audio application can be built upon software like BitTorrent?
**UPDATE - chuckdarwin pointed me to the streaming audio of the broadcast on KPOJ AM 620 in Portland. I will have to check to see whether any of the other stations have their own streaming in place too, as it might spread the burden around a bit...**
