Language wikis

I noticed that the roadmap has been updated that opensuse is about to release language wikis in french, german, spanish, and we were told earlier that this would be like the Wikipedia way of doing it. This implies that each language has its own Wiki database, and interwiki linking will be supported. I know that time will tell, but is the Image: and User: namespace shared across the different language wikis? Otherwise wiki users home pages will belong to one specific language, and all images will need to be uploaded for each langauage. Pflodo
