On FreeBSD, CARP would be the natural choice, seeing as it's standard with
the system. All you need is to build a kernel with 'device carp' added to
the config file and to have read the carp(4) manual page. Then just add
ifconfig_carp0="vhid 100 pass XXXXCENSOREDXXXX 192.168.23.45/24"
to /etc/rc.conf on both machines. Reboot, et voila: the 192.168.23.45 IP
will float between the two servers.
