If you’re just building an mp3 player and worried about zapping a single address, podcasting on nostr is actually quite doable. What I’ve been finding quite problematic is how you handle splits. Imagine if someone zaps by opening up CashApp to pay an invoice. Now imagine doing that 16 times per zap to pay each split. Until splits are handled more elegantly, I think anyone interested in podcasting will stick with the tools PC2.0 has developed.
