Dynamic Object Temporary Stop/Disappearance Notification/Permission

      A method is disclosed for dynamic object temporary
stop/disappearance notification to the affected parties and
solicitation of permission from the affected parties.

      The disclosed method uses the Object Request Broker (ORB, e.g.,
IBM* System Object Model (SOM)) as a notification mechanism to have
the programming object, that is going to be temporarily unavailable,
notify the interested parties, the list of whom is maintained by the
object itself or by the ORB on behalf of the object(s).

      The programming object about to become temporarily unavailable
would be notified by the element causing its unavailability (such as
human user, operating system, or hardware), and then signal the
interested parties.  If a programming object is unavailable due to a
network connection failure, the notification to the interested
parties would come from the ORB, which by its nature would be aware
of network outages and loss of object connectivity.

      On restart/reappearance, the affected object or the ORB would
notify the interested parties about termination of its outage.

      Additionally, for temporary object unavailability due to object
software maintenance, or in other cases where temporary
unavailability may be postponed, a permission scheme could be
implemented.  Before becoming temporarily unavailable, an object
would solicit permission to temporarily "disappear" from other
