Could you build this?
Partial The core RSVP creation interface is simple, but implementing decentralized federation across independent server instances requires non-trivial protocol and cryptographic engineering.
What it would actually take: Requires implementing a federation protocol (like ActivityPub or custom peer sync) with asymmetric cryptographic signatures for server-to-server authentication, background queue workers for inbox/outbox delivery, and conflict resolution across decentralized instances, typically built using SvelteKit/Node.js and PostgreSQL.
