I don't use it for this, but I host my own MoinMoin instance; on any linux machine enabling apache is a couple of lines of config, and then moin is just download, unzip, and add a couple more lines to the apache config (and make sure mod_wsgi3 is installed). It's an old and probably horribly out of date version by now, but that doesn't matter when I'm only allowing access from 127.0.0.1.
