In an effort to start some serious discussion on this, I present herewith some pros and cons of granting some form of commons adminship to wikipedia admins (including en, de, fr, and possibly other large wikipedis).
Pros
1. The wikipedias would benefit from better handling of commons vandalism that affects them. In particular, prominent non-main page vandalism could be addressed more quickly. 2. Commons would benefit from an influx of editors. Wikipedia editors would be more willing to become involved in commons knowing that they need not spend some weeks or months "paying their dues" as a non-admin editor. 3. The process of transfering suitable images to commons may go faster, benefitting all projects, due to an atmosphere of increased trust. 4. Wikipedia editors would become more aware of other languages and sister projects by virtue of working with their peers from these projects at commons. 5. I believe that there would be more rapid growth at commons, which I believe would be a good thing.
Cons
1. Some care would have to be taken to be sure that wikipedia admins are familiar with the differences between their wikipedia and commons, particularly the multilingual environment and the more restrictive copyright policy. A page on the differences between commons and each of the major wikipedias could be written to address this, much as was once done for h2g2 an Everything2 authors joining Wikipedia. 2. Some existing commons admins don't support the idea. 3. The "small wiki" culture at commons would change, and some people who moved to commons due to frustration with the size of their home Wikipedia may find that discouraging.
