We’ve got the PodShow PDN working with CastBlaster and at least one standard blogging app. If you’re working on the authoring end, take a minute to review the metaWeblog API and especially the newMediaObject call. Our implementation hews very close to vanilla metaWeblog though there are a few podcast-specific aspects to how we use the standard function calls. I’ve drafted a developer doc and am tweaking it in preparation for review. More to come.
