I'd like to second this request. I have a much simpler setup - using 
keepalived between two boxes in a master/failover config to maintain a 
service oriented VIP for DNS requests.

'query_local_address' works fine for outgoing traffic from the systems - 
queries are sent using the bound VIP - but answers to requests coming in 
from the network to the VIP are sent out using the systems' own host 
IPs. This causes complications with some other networking configurations 
(ie NAT), and it just simply a pain to have to deal with.
