MoinMoin has released moinX, a MoinMoin wiki for OS X that runs easily on a local machine, or can be put on the Net. Because it runs with its own server (Twisted), it doesn’t need Apache and is easy to configure. I had it up and running in less than a minute on a Mac PowerBook. MoinMoin has some nice features for writing and for teaching writing.
Some reviews: MoinMoin has a WikiEngineComparison chart that links to other considerations and reviews, including one by thinking space.
