| Is there a way to save only updated information?

  How about only saving changes by appending to the file?  This will in
  effect be a transaction log and you can even achieve real transactions by
  saving `begin´ and `commit´ forms so you can save changes made in each
  update method and then finalize them.  Every once in a while, do a full
  save of the database.  All of this may be accomplished with a meta-class.
