what about a dynamic list? (kind of cache)
on call of a class the path can be in the list and all is fine.
but if the class is not in list the path can be build up from classname 
and inserted in list if it exists.

and keep watch about removed extensions and classes:
who will clear the list from unavailable (and unneccessary) entries?
