Interlanguage linking doesn't do all that much. You can't transclude templates and images across as it is, and can't intermingle content any more than you would between any other two wikis.

It makes sense to maintain some kind of similarity in badges and the like, but if you desire further connection (sharing resources directly) that's something I've never seen before. I would be interested in it myself, but I don't know how it would be done. Contact Staff, perhaps? Let me know if you're successful, I'd like this myself.
