If you don't want Spread to use broadcast or multicast then simply put
each Spread daemon into a singleton segment.  For example:

Spread_Segment {

Spread_Segment {

Spread_Segment {

This will cause each daemon to use UDP unicast to communicate its data
to all other daemons.  So, each sp_multicast() will translate to (N-1) UDP
unicasts on the network.  This is, of course, suboptimal.  Preferably,
if you have the capability, then you should get multicast or at least
broadcast to work between the daemons properly.
