[use of wikimedia.org for logins]
No, that wouldn't work very well. Cookies are domain-specific, and so people need to be on the wikipedia domain so we can set a .wikipedia.org cookie.

Fair enough. A Wikipedia-wide login would still be neat though (along with database integration; I guess it makes sense to have each Wikimedia project to have its own database/login).
