  OK.  Where do you think that Reply-Message will go?

  A better question is: What do you think the module should do with the Reply-Message?

  The module works as documented, and uses Reply-Message to do challenge / response prompting.

  If you want to do something else with Reply-Message, explain what you want to do.  And why.
