say I zap a note with 5 zap tags/recipients. is my client prompting me to sent 5 different ln transactions to 5 different lnurls?
Prism creation is made possible through this often overlooked part of the zap spec https://github.com/nostr-protocol/nips/blob/master/57.md#appendix-g-zap-tag-on-other-events
This part of the spec allows you to add multiple zap tags to a single note, each with their own relative weight split.
This is essentially a prism, our service simply coordinates the creation of these zap split notes.

Yeah, the client needs to support zap splits, but essentially you fetch invoices from each users, lighting address, and pay all the invoices.
Currently snort, amethyst, and http://zapper.nostrapps.org support paying zap splits.
