Well, that's something for the root server operators to think about and discuss amongst themselves. I know several of them are reading this list, and may be reading this thread. 8-)
Plus, A is verisign so any hopes of cluefulness or working for the community are fading fast!
Still doesn't help .ORG, which is 100% anycast and thus has no DNS-based redundancy (see my experience elsewhere in this thread).
It does - there are two! Yuo just mean less than 13 as per the root. What is the maximum number you can fit in a single NS reply for a 3 letter tld such as .com/.org ? (Is it still 13? I'm not familiar with the DNS protocol at that level) Steve
