CachedPublicKey needs to become CachedRemoteUser. Add the user's inbox and outbox URLs to the model.
Can I easily create an Activity for creating a local Article? (Bear in mind that this instruction might have come in via the user's outbox, rather than locally.)

New challenge: Auto-send Accept responses for incoming follow requests.

Activities need to allow lists etc. Can't we just store a JSON blob or something?

Delivery needs to be implemented. What's the longest chain of lookups?

We'll probably need a Delivery model.

XXX This should all be done through Celery. How good is Celery at task resumption even after a reboot?

Let's look at validation, done using Celery throughout.

We create an IncomingMessage, and save it, always. Then we ask Celery to do the rest: validate_task.

One single function. Based on CachedText; this does the fetch etc.

Is there something weird going on with our webfinger implementation?
