Not what I'm talking about.

What notifies a cache that it needs to fetch new objects from a RPKI
repository?  As best I understood, it's largely done on cron jobs now.

I could readily see a BGP signaled "This AS has a manifest with a newer
serial number" being passed back to rpki-rtr so that it could kick off
rsync (or whatever).
