This is one of the end-goals of Lightning.Pub, and why we put Nostr-based "offers" (and webhook triggers for them) on the node side.

The problem with self-hosted stuff like Start9/Umbrel is that providing SSL/Clearnet access for the normal consumer requires a somewhat complex network config, particularly when on a residential connection.

This means the store-front side is probably best living on a traditional commodity web-host externally, while the business logic (lightning node) remains self-hosted.

Nostr solves the networking problem by just pasting an nprofile into the store front, Lightning.Pub then solves the callback-on-payment-confirmation to the ecommerce fulfillment flow.

Too much to do... we're happy to hold anyones hand that wants to take a shot at an ecommerce interface backed by a Lightning.Pub
