Jim Yes, but from what I've seen most people who want geographically diverse DNS these days use a service which offers it eg. Dyn or one of the other big DNS providers. I know you're doing it for your personal domain, but that's hardly surprising :)
Registry operators - particularly ccTLDs - do this all the time, but I don't see many registrants of domains doing it anymore. And I thought this paper was about domains more than domain registries?

For instance many TLDs rely on a mixture of name servers they operate themselves, some provided by other TLD registries -- I'll slave your zone if you slave mine -- and others from commercial anycast providers. It might be true that the majority of registrants just stick with whatever DNS is offered by their registrar but not all of them do that. Clueful ones certainly don't.
