be-BOP is a free and open-source, peer-to-peer monetization platform built for communities and creators. It combines e-commerce, point-of-sale (PoS), subscriptions, crowdfunding/peerfunding, ticketing, donations, and pay-what-you-want models — all under one roof.

Is using a LND node as backend and I think it could be adapted to phoenixd also.
Would be interesting if it could be working with a Lightning Pub backend. What do you think @justin_shocknet ?
