Don't touch Linux myself - I'm using OpenBSD on our firewalls and FreeBSD on our web and database servers so CARP seems like the way to go. Interface failover seems pretty straightforward, I'm more concerned now with service availability, ie (lig)httpd and the pgcluster loadbalancer. That's why a combination of CARP and monit looks promising. Ashley
