Some standard Zope document types have a 'history' tab. Apart from the terse 
UI (which you can replace) and the fact that it doesnt contain *all* history 
once the storage has been packed, would that capability satisfy you?

DirectoryStorage has the capability of storing extra history for specific 
classes, designed for exactly this purpose. If you are not tied to 
FileStorage check out http://dirstorage.sourceforge.net/keepclass.html
