Well...
I got the MoinMoin parser running in django, and now have a mostly working wiki implementation using the MoinMoin parser (yay!), I ended up using the text_xml rather than text_html formatter for MoinMoin, this turned out to be a good idea, and meant that I didn't have to worry about them thar themes that get called otherwise. It still needs a few mins more work to actually make it a usable wiki, but the proof of concept worked.
Next on the list: writting a nice blog engine and moving my blog over to it rather than using pyblosxom... actually, I can do this one very trivially for a straight port of the current blog :)
