Wow, what a joke. They're basically saying they have the patent to not only podcasts, but RSS, since that's the delivery "apparatus" for podcasting, and if they say that, then it basically includes ANY blog in existence that has ever posted a video or audio file, or any sort of "media"... so you're talking about not only those folks who call themselves podcasters, but everyone else with a blog, too. It's not just insane, it's preposterous. And it'll never go anywhere because it's just too vague.
Now, excuse me while I go draw up a patent for websites.
