wikipaper

Most wiki systems incorporate equation editing and other basic formating stuff like figures with captions and sections/subsections. These are the same basics of any latex formatted paper. Are there any scripts out there for converting wiki pages to latex?
One can imagine an environment where collaborators can all work on a paper in a wiki environment but with the addition of other unpublished appendices. These could have related articles, data, conversations (like a message board), etc. Seems like its all there, just need a converter.
