I'm currently being a "mad scientist" 🤪 and experimenting with a multi-tenant #ActivityPub domain-independent server implementation. One account can use multiple AP C2S (Social API) client apps similar to PixelFed, PeerTube, and Mastodon (with others possible). Server tenants are lightweight, good for single-users with a custom domain, and should be portable to other servers (similar, in spirit, to ATProto or SoLiD pods). Proof-of-concept only at this point. I'll blog any interesting findings.
