Podosphere PR?

I think podcasting has all sorts of interesting implications for PR – some good, some bad. 

As some folks have already noted, the roll-out of Yahoo!'s new podcasting service started in the podosphere first, then it branched out to the MSM.  If this wasn’t a product for podcasters, I don’t know if this approach would have worked, but it begs the question: How many PR folks out there are actually listening (literally) to and perhaps engaging with the podosphere?
