Is there a good WikiField for django models?

Question

Is there a simple way I can add a "WikiField" to a model I have in my application?

I think the most important requirements are:

• A text field that can be added to any model.
• simple wiki markup or editor widget that enables text formatting and easy insertion of links and images.
• saves revision history with author information, and easily allows reverting back to any previous version.

Just to explain what I'm trying to do: Imagine you have a bookstore app. Most of the Book model's data come from the store's catalog. Now we would like to add a block of text that is a community wiki, so that users can write the plot summary for example.

How about a combination of django-reversion and django-tinymce, or Markdown if you prefer writing markdown?

I've not come across any field types specifically for Wikis, but with those components writing one really shouldn't take too long.
