Hi, I'm looking for someway the override the export/import for persistent Zope objects. For instance having an ExtensionClass based class I could override the the __setstate__/__getstate__ or __reduce__ methods to change some of the attributes. This would be useful for serializing objects that stores some parts in the file system (for instance "External Files"). But due to the persistent nature of ZODB these methods doesn't work as usual. Is this at all possible with the current Zope/ZODB?
