Almost all of the expos and conferences that I've come across recently contain at least on segment on monetizing podcasts. Podcastday 2006 is no different and I hope they put up podcasts of that segment at least.
I ran across two books today on the same topic: "How to make money with your podcast". Sigh...everyone is making money with podcasting but podcasters. I'd love to hear guys like Ewan Spence from TPN talk about how it's really done and not individuals hawking their books and services.
One thing the networks can do well is attract large advertisers. Presumably, they're interested in passing any advertising money back down to podcasters and perhaps that's the only real model that will end up working. Only time will tell, but it's a hard to live through the days as this model is sussed out.
