There is no special case policy for (unicast) ccTLD name servers, for major search engines, big software vendor download sites, etc. -> find an upstream provider, get an IPv6 address block, and enter that in the relevant DNS zones. Of course the underlying question returns to "how to do IPv6 multihoming for A Special End Site".
I think gTLD's and ccTLD's would certainly qualify for their own IPv6 space (for the purpose of being able to do proper multihoming).
I strongly disagree. The DNS protocol has its own built-in redundancy, and changing addresses for TLD servers is not prohibitively difficult. So I see no reason why they should have PI addresses, especially since there is a significant number of TLDs and they all use several addresses. If those addresses would all become PI this would probably double the IPv6 routing table size at this point. (Granted, it's very small now, but still.) If TLD servers are anycast that _could_ be a reason for giving them PI space, but I think the TLD community first has to come up with coordinated plan for this, rather than just start giving out PI blocks and play "voldongen feit" game. (Sorry, it's monday morning, can't think of the English translation. In French it's "fait accompli".)
