Ones own namespace for web repository objects: In the Web-Repository we have created a development class, ZGXT, as you have suggested in the Documentation. Does this still work if we put it in one of our own namespaces, e.g. 
/KIBF/FA
or would there be a problem with the backslashes?

As of GuiXT version 2003 Q2 3, it is possible to use your own namespace /xxx/ for web repository objects.
