It's not fancy but we just run a perl script to generate our  
catalog_befores for each catalog. It allows us to do stuff like above  
and more. We keep many site settings in a configuration table editable  
via an Interchange based UI by non-technical people. We simply call  
our "make_ic_configs.pl" script from out interchange startup script.  
We do a similar thing with Apache.
