With the quotes it seems to at least now start up and listen on the 
right interfaces - thanks Gergely!

Looks like the problem I was seeing was that quotes are required for 
specifying IPv6 addresses, but are not required for IPv4 addresses.  For 
example this config loads fine:

source net {
         tcp6( ip("2001::20") port(514) max_connections(25) );
         udp6( ip("2001::20") port(514) );
         tcp( ip(192.168.10.12) port(514) max_connections(25) );
};

Perhaps this can be added to the admin guide, as the behavior of this 
parameter is inconsistent, at least, between v4 and v6.

Thanks,
Reuben
