we use CARP to balance and failover some webserver pairs. We also use
it to balance our internal DNS caches to our internal clients. The
only drawback is that once you pass a router, all traffic from that
router will go to a single CARP host -- ie, you get failover but no
balance.
Other than that, it makes upgrading systems nearly invisible to the
other servers. For critical things like DNS, this is a big win.
