For the central registry, could we define a reverse DNS lookup to verify the hash's uniquesness? Even if the first reverse DNS probe proved not to be unique, one could append a well-specified computed string, such as "0", "1", "2", ... to the domain name on each successive attempt, until the hash's uniqueness was confirmed.
