We are using LVS Linux Virtual Server, a Linux kernel module with the packet ldirectord. It's a great project. Ideal for DNS resolver, easy to configure, cheap and it has in "direct routing" modus a very high performance. With this setup you have one IP to your clients. But each "real server" has it's own IP for outgoing queries. No NAT.

Hey guys, This is a pretty open question... But anyone forsee any issue with the following setup: Bunch of DNS resolvers that are behind a load balancer, load balancer is presenting anycast to the clients for resolution, dns servers behind load balancer only have private ip's on their interfaces, load balancer has a single nat address for the outgoing queries / responses.
