List of various ways that content synch can be implemented

1. Namespaces - all edits in a custom namespace are published to other wikis in real-time using interwiki tables and scary transclusions
2. Hooks - use a "hook" extension that does sync "on save"
3. Server Scripts - cron jobs + pywikibot/mwclient
4. Extensions - extensions like Page Exchange/Page Importer

Have you checked out the Sync extension?

yes, but it's been a while. When I last checked it, it wasn't possible to use Sync on private wikis that use PluggableAuth for authentication and authorization. Has that changed? Is there a way to use Sync such that allows local accounts to bypass PluggableAuth?
