If the feature is restricted to only work on wikis that share a single login then the security risk is removed. It may also simplify the code, e.g. instead of having to pass the images via XML/http it could perhaps copy them directly on the disk. My point was that in situations where SUL isn't available (e.g. current WM-wikis, or non-WM wikis in general) then there is a big risk in opening up this kind of functionality.
The most obvious application (and probably the only significant application) of this feature (deleting the file from the source wiki) would be for transwikiing media to Commons from other Wikimedia projects. As such I think it would be safe to confine the feature to our specific conditions, which include a central location for media files, regardless of which wiki they are on (so requiring no moving of files), and in the near future SUL.
