Definitely. However (and I'm not saying it has to be this way ;) if the user database were a Django app, and there were REST APIs that the core could call to do updates, then when something in the core changes, an event would get triggered that would make the RESTish call to update the user database. Similarly, when something in the user database changes that the core needs to know about, it would call the core's REST API to make that change. We would have to design something that would be robust enough to deal with failures, but I think it could be done. >2.
