If you want to kill this thing (and I'm not recommending you should---I don't personally care), the best way to do it is to find a document published anywhere in the world before November 2002 (1 year before they filed) that has all the elements of their claims. It doesn't matter what the abstract is, or what the title says, or what's in the specification, or even that the inventor calls it "the podcasting patent." All that matters is the claims.
