Hi!
Issue with Wikimedia logos violating Commons policies re-appeared
again on Commons Village Pump.
But logos should be shared across Wikimedia projects. Otherwise
everybody will have headache with supporting multiple copies of same
images of different projects.
I think MediaWiki contain technical ability to solve this problem. As
far as I remember SVN comments, new file storage class allow to
support several shared file servers like Commons. So Wikimedia logos
could be moved to dedicated server. Access to this server could be
restricted for avoiding vandalism/unapproved logos changes (for
example to stewards/board memebers).
Just thoughts,
Eugene.
