Vladi The subject hasn't really come up yet, and I expect it will probably have to wait until Flarum is stable before we can expect any real progress on integrations.
However, this is something I'm also hoping we can look into at some point, as I'm currently working on a couple of Joomla sites that I would eventually like to integrate Flarum forums into. I would be interested in the possibility of embedding Flarum into a Joomla site, as well as user account synchronization.
Edit: It seems I was wrong ... Joomla was mentioned once before, way back in May. But it deserves a thread of its own!
(Moving this into Feedback so it can be handled as a feature request.)
