While brainstorming (daydreaming?) about what a graduation from apple and google would look like, I started wondering about how Apple Push Notification service (APNs) (not sure what the android equivalent is called) works behind the scenes. Perhaps something lite could be implemented with custom payloads over #xmpp or maybe it would need to be more of a custom service. 🤔🙃
(I initially thought of #mqtt as a lighter coordination server, but persistence might be an issue there)
