[Zope-dev] Storing session objects in a ZODB

I want to store the session objects (from CoreSessionTracking) in the ZODB so that users can save preferences (set in a Session) and call them back later. Just thinking that the easiest way to something is to pickle it, but pickling it in the ZODB which then pickles it, seems daft. Someone suggested I could just _setObject into the ZODB, but don't I still need to make a class wrapper around this? Has anyone tried this? I couldn't spot anything in the CoreSessionTracking API that obvious... Cheers. -- Andy McKay.
