However it is stated on the homepage of wikipediafs that the project is not maintained, it works! The only one change one has to make is:

user.py:56:        self.login_page = “%s?title=Special:Userlogin” % self.basename

into

user.py:56:        self.login_page = “%s?title=Special:UserLogin” % self.basename

(note the change from Userlogin to UserLogin)…

and now it is straightforward and easy to edit the wiki with vim… I will write probably a plugin to jump to links automatically. I wish one day there will be fuse fore wince and I will be able to edit wikis with vim on mobile

Please note that wikipediafs is a userspace filesystem and is mounted with help of http://fuse.sourceforge.net.
