Make your Product a Folderoid (zopespeak for a Folder Object) that
contains it's own user interface which the manager can edit.  Your
__init__ function initially loads the documents off disk into the
Folder.  Confera and NotMail both do this (Confera does it a little
smarter).

I'll let someone who has more experience with those areas answer this
one. :)
