Yes, I noted that the addresses were the same. Thinking further, this could
get tricky if domains example.com and example.org are managed by different
registrars because both will have to keep track of the IP address associated
with their version of the name server.
Maybe there's another approach that eliminates this potential
multi-registrar fiasco (thanks Adam for the ping on aliases). Suppose a
name server's unique primary key is a host name (ns1.example.com), and
instead of allowing registration of other discrete name server objects with
the same IP address we add an aliasing requirement. That is, there's a
single name server object, but the object has attributes that identify both
IP addresses and host name aliases. Aliases can be added only by the
registrar sponsoring the primary host name, but the aliases can be host
names registered in other TLDs. For example, ns1.example.com could have
aliases foo.example.com, ns1.example.org, or ns1.example.com.au.
A records would be produced only for the primary server name and those
aliases that exist in the zone's TLD. Using the example above, the com zone
would contain A records for ns1.example.com and foo.example.com, but A
records for the other aliases would have to appear in their respective zone
files.
Does this seem like a suitable compromise?

And you noted that the IP-addresses were the same?
