Blog + Wiki

In light of some recent experiences with WikiWikiWebs , I'm beginning to wonder if MovableType is really what I want in a weblog tool. I think I'd actually prefer a hybrid wiki. The wiki would identify each node as either a regular wiki entry or a weblog post (essentially a wiki entry tagged as being a "journal entry" and with an associated timestamp). The front page would still list weblog posts in reverse chronological order, and there would still be a weblog post archive, but other than that, it would be a regular wiki.

There are certainly people playing with this idea already, for example, Martin Fowler's Bliki . However, I haven't seen any packaged solutions a la MovableType. Has anyone seen such a thing, or would I have to roll my own?
