When I was developing WP-iPodCatter, it seemed straight-forward enough to tie WordPress’ enclosure detection with the Comments RSS feed to create a comment podcast, or comment-cast.
I didn’t have a personal need for this feature (so it’s not as fully developed as the others) but I thought it’d be neat and it was easy to do.
Plus, the thought of a podcast with distributed hosting, on topic, created by fans of another podcast seemed like an interesting way to bring the threaded comments to audio.
Here’s the scenario, I publish a podcast. You take it, translate it, record it into a language you know well, and republish it as a comment to the original.
Subscribing to the comment feed will automatically deliver the translated files as fast as they’re published.
Could be helpful. Could cause more and bloodier wars.
