> Yes, I can see that before too long, over-cautious administrators will block DNS lookups of names that aren't in the long-established TLDs like .com, .net and .(ISO country code). That will lead to the establishment of a mirror domain such that X.mirrordns.com resolves to the same as X.
My fear is that these administrators will block the lookup of every non-traditional TLDs *except* .google, .apple, .facebook and .docs. Good luck requesting an exception to another TLD that does not belong to a big brand.
