right on! for starters I have very little public facing material yet. the basic premise is to represent a feed as a pubkey, where each item in the feed is mapped to an event. there is already working POC of this created by @fiatjaf.com at https://github.com/fiatjaf/relayer - check the rss bridge subcomponent.

I am working right now to get my own implementation up and working. for the moment, you can see a half-assed attempt here: https://nostr.io/podcasts  the page is poorly formatted, and I'm still tinkering with every aspect of it. but the basic concept is there. I aim to support normal RSS feeds along with podcasts. you should see the mp3's in those podcast episodes as media controls rendered natively in your browser.

at the same time, I'm working on a nostr backend, where you can get a link to an RSS feed of your events. look on the left side at the RSS icon: https://nostr.io/p/b17c59874dc05d7f6ec975bce04770c8b7fa9d37f3ad0096fdb76c9385d68928

and finally, I have a PR into the nostr protocol github to add "resources" to nostr events. I am already using that feature in my demo podcasts link, but it's not part of the protocol https://github.com/nostr-protocol/nips/pull/43

I'm happy to talk further at length about any aspect of this that you may be interested in.
