Well. The easiest solution is to test if something set up by 
importVarious exists already. CMFDefault looks e.g. for the 'Members' 
folder:
http://svn.zope.org/CMF/trunk/CMFDefault/setuphandlers.py?rev=68358&view=auto

But that solution is not very robust. If the site is modified and 
'Members' renamed or removed importVarious will be run again.

The only save solution that comes to my mind is to use a small file in 
the profile that controls if importVarious should be executed.

Great! That's at least a start.

I'm afraid this is a big project. I guess a single person would need 
several weeks to create a working prototype and several months to write 
something releaseable. So we would either need sponsors that pay a 
person full-time or a team of people that are willing to make 
significant contributions.
