I’ve brought up payment intervals to some core nostr devs.
it’s just the premise that a zap would be split with the relay it’s on… when I could of read it from 3 relays I’ve connected too… and when after that zap occurs it could end up on another relay. Doesn’t quite compute with how nostr’s reach fundamentally works.
Alternatively, a relay could let you link a LN wallet, like fountain fm does.. and set up payment intervals, and offer to split that funding through current zaps to the notes that are sent to your client.
