i think it's as simple as adding an arp entry (with the keyword pub)
for the ip address so that the machine will advertise itself.
arp -s hostname ether_addr [temp] [pub]
fwiw - i always put the aliases on a physical interface, not lo0, but
that requires me to specifically enter a route to that address through
127.1 so that i can get there from here.
looks like two steps either way.
