  Aye, it's up to their system to automagically create the glue records on
demand.  The tld itself really doesn't give a rats rear.

  Becouse glue records can resolve direct from the tld servers.  THis magic
means your creating A records directly in the root servers.  Now image
someone adds a glue record for www.google.com is the .com tld.

  Since most registrars are lazy as all hell, they don't want to check, and
make it a manual process if the DNS server itself isn't under the domain
that it is serving DNS for.

A quick test shows a couple random domains working as expected:

  Aye, this is becouse it is automagically asumed that if the DNS hostname
of the DNS server resides within another TLD, that the given TLD for the
name server itself is responsible for resolution of the domain.

  Hypothetically, if I have:

  larry.org
    NS ns1.moe.com

  moe.com
    NS ns1.curly.com

  curly.com
     NS ns1.curly.com
  A Record - ns1.curly.com - 82.123.232.12 (GLUE RECORD)

  This is perfectly legal, and ASSUMES that ns1.moe.com can be resolved by
ns1.curly.com, even with no glue record for ns1.moe.com.

  Now, it's bad practice, becouse if ns1.curly.com goes down for whatever
reason, larry.org is screwed.  But heck, this is the three stooges here, one
goes down, they all go down, right?  :-)
