Forgive me for this sidestep, but you are saying that Windows/IE actually ignores bad IP addresses if a site lists multiple IP's in a DNS lookup? I tried this approach for some redundancy a couple years ago and it didn't seem to work as you suggest. If it has indeed changed to work that way, this will help one of my clients immensely.

The versions of IE I've tried have been very good at this although it doesn't work for other stock windows apps. You may need to make sure that ICMP 'unreachable' packets are not firewalled so down hosts are detected quickly. You can test it easily by setting up a dummy DNS name with a bunch of A records where some point to working servers and some don't.
