What are they smoking?

And then Verisign starts using multiple IP addresses and rotating through
them. And then they stop giving any other clues that it is a wildcard
record. Great. Just what we need... To be in an escalating war with the
people running the root nameservers.

Since it is clearly in Verisign's business interest to make it impossible
for you to tell when you've been handed one of the wildcard replies, I don't
see this stopping any time soon.
