The problem here is that we would need 100s of unbound and their primary 
role is not to act as an authoritative server, but as a recursive.
So divide the currently used 8/16GiB of cache with 100s and you will 
start to get the point (not talking about the increased complexity of 
starting, configuring unbounds and the packet filter).
It is a lot more efficient and simpler to change back to bind then...

This is not an internal/external stuff.
