A little further experimentation indicates that this was indeed the 
problem:  saned seems to have an undocumented dependency on 
being able to perform reverse DNS lookup on IP addresses.  It's 
possible that this only happens if avahi and snmp support are not 
compiled in.  Regardless, adding hostname and IP data for the client 
machines to /etc/hosts caused saned to suddenly start allowing them
to connect.

Anyway, thank you for your help.
