TLD anycast clouds?

[Steve Gibbard <scg () gibbard org>]

I'm attempting to come up with a list of all the top level domain DNS 
servers that are anycasted.  I already know about the anycast clouds run 
by PCH, Neustar, Verisign, DENIC, and UltraDNS, and .mx appears from 
traceroutes to be anycasted as well.

(I know about the anycasted root servers as well; they're out of scope for 
this question...)

Are there others that I'm missing?

Thanks,
-Steve
