This is the first product I’ve seen that’s been developed specifically as a “podcast console”. It comes from a company called TinyScience and I’ve included a link to a quicktime demonstration of the software. It’s Windows only and requires the .Net framework installed. I haven’t used it yet but the demo looks pretty good for a basic system.
BTW: Their website renders like garbage in Safari and I’ve already complained. James Prudente the author of the software and website in question sent me a very nice response saying he’d try to fix it ASAP.
