Define "truth."

Seriously, keeping this engineering, what is the difference between 
"crafting replies" to queries (which some call lying) and rapidly 
updating the zone?

Would cache operators prefer that the TTL is dropped to nearly zero 
to force more cache misses?

The goal here is to retain the authority of the authority servers and 
still make use of caching.  If you increase the synthesis of answers 
in caches, you are removing authority from the authoritative servers 
and placing that in the caches.

Debating the utility of rapidly changing zones, alternate forms of 
answer synthesis, and "lying", if taken up, should happen in a 
different form than this subject line.  For now, if we empower 
caches, we stifle exploration in the authority server space.
