I don't understand the first question fully; a website than can embed nip99 or a website that displays your plebeian shop?
yes you can add as many npubs to your v4v, each with a custom split 🦾

The first question. I'm looking for any other project or code base that is embedding nip 99 listings outside of the platforms listed here. I mean I guess I could probably just use the assets in your code base, would need to review.
Shopstr, conduit, my old build https://cypher.space supports the kind I think a couple social clients are also looking at it.
