I'm designing a network in which a host running UNIX System 5 and
using TCP-IP over Ethernet sends the same message to 16
workstations.  Rather than send the same message 16 times, would
like to broadcast the message to the workstations only once.
Can't use UDP because the workstations have to acknowledge
receipt of the update.  Do you know if there are any flavors of
VMTP that will do what I need?
