Is it possible to put couple of BIND Servers behind a load balancer and both
of them act as authoritative to accept DDNS?

Question to BIND Engineering? Is there a plan to add Multi-Master
functionality to BIND in future?

It may not be big deal for people who don't use BIND as Active Directory DNS
Server, but its single point of failure, if BIND is used in an AD
Environment since DDNS requests will be send to single master.
