Rush is Pod-Casting
The fidelity is better (48k vs 20k online), but there's no theme, bumpers, not even the end of segment sounder. And you get an automatic downloader to fetch them when available. So far so good. (If you want to see the opposite, a totally screwed up multi-media enabled site, visit www.nascar.com.)
