This is true, and it bites us via the user database. This recently came up in a conversation about the authenticating proxy. There has been discussion about a centralized user database, and I think eventually we'll need something like that, whether it's part of the core or a separate component. >ISTM the core exports pretty good information, but it has no ability to grant >privileges in the other components.

Agreed. Within the core, we have a set of events that get triggered when certain things happen, like a user gets subscribed to a mailing list, etc. What we could do is set up a pubsub that gets notified when these events happen, so Postorius or any other component can be notified when the user database gets updated. >I wonder if we might not have been better off using an object-oriented >database like MongoDB for the core. That would allow adding >components from external sources as the external sources require. Perhaps, but for now that ship has sailed. It's certainly not a good idea for non-core components to be mucking about in the SQL database. Let's think about the APIs we'd need to build to provide better communication between components.
