But in order to use shareduploads I have to create a
NFS connection to
the public (remote) wiki, that's at least the suggestion from previous
comments on this thread. And NFS seems overkill if all I want is to
transclude articles.
In the case of an internal wiki, setting up the connection may well be
more work than it's worth. If it were a public wiki, you wouldn't
really have much choice.
