1) Create a lo1 or alias on lo0 inteface with a /32 of the public
   IP address
2) Create a static route on each machine, for the public /32, via the
   private /32 (in the /24 or whatever)

e.g.:

machine1$ sudo ifconfig lo1 create
machine1$ sudo ifconfig lo1 inet 129.144.100.100 netmask 255.255.255.255 up

machine2$ sudo route add -host 129.144.100.100 192.168.100.100

And vice-versa.
