I have been writing a plug-in to enable me to crosspost to the wiki from here.
Whenever I give a posting the category wiki, it will add links to this posting to go see or go edit a page in the wiki of the same name, when generating the index page.
Also I got WP to post to the wiki. I create camel case names, from the title of the blogpost, and then create a new wiki-page with that name.
At first it did not work together with the camelcase plugin, but now it does. So when I now camel case the title of this post here, it will link to the wiki as well: WikifyingTheBlog should do the trick.
The code for the plugin is public domain and available at WikiAdd
