Complete MediaWiki/vBulletin 3.5 integration: is this possible?

[Cyburbia]

I've seen a lot of hacks and kludges for vBulletin/Mediawiki integration, but most seem to fall short - it might be a collection of mods with no step-by-step instructions on making the whole things work, or it may be an awkward bridge that requires separete logins, or it may require user name changes to remove characters MediaWiki chokes on.

I don't think I can be the only one who is DESPERATELY seeking a true integration of MediaWiki or any other MySQL/PHP-based wiki with vBulletin 3.5, similar to what was done with vbDrupal, or similar to the integration in commercial software like PhotoPost. This is what I'm looking for:

1) It has to be real integration; not a bridge, and more than just simple user authentication.

2) The wiki uses the vBulletin user database, and ranks and permissions system. It's not something where vBulletin login information is copied to the wiki database, and users may have to log into both, or automatic side-by-side logins. Rather, it should be like the Drupal and Photopost integration, where it's completely seamless from the user's standpoint.

3) Existing users won't have to change their names. Some bridges and integration hacks require that vBulletin users change their names to remove spaces and other characters that would be invalid in the wiki's namespace.

4) The wiki isn't an old-school system that still uses CamelCase, where visible links within an article can't have any spaces (WikkiTikkiTavi, ErfurtWiki, PhpWiki, others). I want to link to articles about urban planning and form-based codes, not UrbanPlanning or FormBasedCodes.

5) The wiki won't break when vBulletin is upgraded. The wiki should be easly updated, too.

6) No vBulletin code is altered.

Is this even technically possible?
