As someone who spends more money than I should on music from Bandcamp, I'm interested to see if they ever get payments working. I remember people talking about a federated BC alternative, where the 10% platform fee goes to the instance you're on, when they got bought by that music licensing company.

Also, first paragraph under "Integrating with the Fediverse", you put Bandcamp when I think you meant Bandwagon.

Mirlo.space is working on federation too. I think they're not as far along in that regard, but further along in terms of being a bandcamp replacement? Last I heard, anyway. I buy stuff from there, payment works.
