Master/slave was to avoid SPOF -- if the master dies, who cares with a
reasonable expire time.  :-)

So go ahead, setup a VIP...even using free stuff like Linux HA!  In the big
push for virtualization we've deployed N virtual machines behind VIPs doing
recursive DNS and it works fine.  It also lets you upgrade, replace, etc.
any of your hosts with less stress.  I think high availability should be an
onion of many layers similar to security.
