Hi Surely that's not how you do load balancing and I'm not even sure the way you're describing it would actually work using openDBX. I keep the MySQL database synchronised between each of the powerDNS servers and then used a VMware Appliance in front of them to provide load balancing. The appliance I use is this one: http://www.vmware.com/appliances/directory/300 - it uses minimal resources and is stable for my environment. That's just a convenient method for me, you can do it with the pen load balancing software (the link is on the page I've pointed you to). Perhaps you'd be better asking on the powerDNS mailing list about load balancing and synchronising the databases, I've seen several threads on this topic there.
