the data upstream of a recursive does not show end-user ip addresses, 
nor reuse/popularity information. that's why google's privacy policy for is so important. you guys do good work with that -- please don't 
take this e-mail thread as a complaint.

i am not always zero or one hop away from google. but even if i were, i 
would want to control my own RDNS policy, using DNS RPZ. google's raw 
unfiltered service is exactly what i want when i'm on travel, but it's 
not what i want all the time.
