What does that mean? Load balance DNS lookups across multiple servers? Or use DNS to load balance? I've never setup a load balancer for DNS before. Always just had one server and moved the VM in event of failure/maintenance.

I've done this with bind and Microsoft before. PowerDNS has an awsome geolocation plugin, and that probably can be tied to a check to see if the IP is up so it's actually checking the status of IPs to make it more automated.
