We're using pdns to provide weighted round robin (WRR) with a MySQL 
backend (replicating round the DNS servers)

You could have your control system alter the weight or number of servers 
available for a certain A record (based on load/availability) and PDNS 
expose this to the world.

Here's how we got WRR to work:
