One obvious use case is value-splits for blog posts and similar long-form writing. Imagine if every blog post (or book chapter) had its own Lightning address, splitting value to author, editor, illustrator, and proof-readers automatically…
…Another use case is the splitting of nostr zaps. Imagine that every “quote-tweet” that gets zapped results in an automated payment split, passing on 50% (or whatever the user has configured) to the original note. Or imagine a prism that’s created on-the-fly, splitting zaps equally for everyone tagged in a note.
