Or just slave the root zone.  1 million root servers is more robust
than the hundred or so we have today and given the root is signed
you can verify the answers returned.

One can have your own, offical, F root server instance if you want.
A number of ISP already have one.  I think a number of the other
root server operators do something similar.

One can hijack one of the official address and replace the A and AAAA
records with local address.  This one does cause issues for any one
wanting to lookup the hijacked address.

One can use static-stub in named and simlar mechanisms in other
nameservers to send root zone traffic to a local instance.

On can use multiple views, match-recursive and forwarder zones in
forward first mode to validate answer from the other view using
tsig to reach the other view.  You can also us this to get AD set
on answers from your local zones.
