Ummm, I think you're referring to their 3DNS product.
I hear that the smart folks over at UltraDNS also provide an automated
DNS based failover solution as well.  About 3 years ago I set up a
active/active LVS based load balancing solution for a company.  I hear
that it's been up for 3 years handling tons of traffic with no
problems.  Throw in a little scripting for dynamic weighting -- and
you've got a pretty flexible load balancer.
