Whither Podcasting?

I've got plenty of pro audio gear lying around at the house in Wading River that doesn't seem to get used very often, so I'm thinking about bringing a 12-channel palmtop mixer, some microphones and some studio monitors into the office so that I can mess with putting some podcasts together after work hours. I have an idea for a radio show on online marketing that I'm working on. There's a neat device available at Radio Shack that attaches to a phone and lets you pull calls into a mixing board input, so I'm going to give that a go so that I can dial out to people in the marketing business that might want to participate. Stay tuned.
