This section includes portable 'speak' service based utilities.  These 
utilities are being ported from the original WorldVU SPO speak services.  So 
far, only "say", "down", and "vmon" have been ported.  Additional
utilities to be added will include a new non-WorldVU related user session 
announcement daemon, perhaps as part of vmon.  The original user session
monitoring utility was closely tied into the WorldVU user cluster
monitoring system.
