I don't know about the site you mentioned, but another group have
integrated Koha and Greenstone in a different way.
Please see their live cd project page - there are details about what
they did which you can use http://gsdlkohalive.sourceforge.net/
Or you can look at our wiki page
http://wiki.greenstone.org/wiki/index.php/Koha_Greenstone_Integration
These are notes about integration which I got from a developer that was
working on this project. I haven't tested the instructions myself.
