   *
   *  This class provides a look and feel similar to the
   *  TAO::Invocation_Adapter though the functionalities are
   *  different. For the record, IDL compiler doesn't know the
   *  existence of this class. This class is concerned with the
   *  creation and invocation of locate request invocations to the
   *  target object
   *
   * @todo Need to think what happens if the target is
   *  collocated. Looks like there are no ways to utilize the
   *  opportunity that may have been presented.
