[Mediawiki-l] interwiki transclusion with images - second try

we got it to work (big thanks to Liam!) but the solution is not
related to anything in this thread (!?). Just to recap, I wanted to
pull articles with images from my public wiki to my internal wiki
(using transclusion). The articles came through, but images appeared
as placeholders with a link to the source images on the public wiki
(so you could click on it and view the image on the public wiki)..
The solution is to add the below to LocalSettings.php on the source wiki:
This adds the proper scr= attribute to the <img> tag which means that
the transcluded article also pulls through the image.
Make sure you also set the following on the local wiki:
$wgAllowExternalImages = true;
$wgEnableScaryTranscluding = true;
So no $wgSharedUploadXXX configuration or NFS configuration is
necessary at all. Shareduploads enable you to specify a link in a
regular article (no transclusion) to an image that doesn't exist on
the local wiki and force the local wiki to check the image repository
at another wiki (configured in $wgSharedUploadPath and
$wgSharedUploadDirectory) if it can pull the image from there.
Anyone have a suggestion where on mediawiki.org I should document this properly?

I will switch to Linux internally, set up an exact mirror of the public site and try to use NFS over SSH between the two sites ( http://www.howtoforge.com/nfs_ssh_tunneling). I know that Wikipedia is run on multiple, distributed server farms. Are you using the same setup then in order to have all the Wikipedia project sites connect to Wikicommons to transclude/include the media files?
