a clone? perhaps not without a lot of effort.
But you could probably do a post based podcast list. and you could have a form for those who wish to post their podcast info that you turn into a post. And that could even be somewhat automated if you have your form send to an email address that wordpress reads and makes posts from.
so ya, you could sort of do a kind of a clone without too much effort. I'm not sure what benefit it would be though.
