I would expect that OIDs are reliable (in the sense that
they do not change, once associatate), but

  *  they are a very low level feature, difficult to
     access from most Zope parts

  *  they may not be unique
     Think of "mountable storages".
     Then each storage will have its own OID's, interpreted
     in its own local context.
