Wikify WordPress 2.6

I’m really waiting for wiki functionality on wordpress, and I think that “revisioning” feature could give us this opportunity.

I see in codex site (for example http://codex.wordpress.org/Roles_and_Capabilities) that some pages are “marked as in need of editing. And you can help Codex by editing it.”

It would be great if we can select a special category to “wikify”.
Can we “wikify” a category, with the same technique?

I’m waiting for news about this interesting topic…
