Actually nostr is very well positioned for this use-case with being inherently social + blossom servers becoming very common these days.
A way to monetize could be a service that provides extra bandwidth for popular podcasts around the release time when the load exceeds the blossom servers' capacity. Alternatively this task could be done in a crowdsourced way: allow anyone with bandwidth earn sats by providing the extra bandwidth, and you can take a cut for managing the connections. So many ideas and possibilities to explore.
I'm planning to release one episode of a podcast for my local community in January to shill nostr, and see how ready people are for this kind of goodness.
