i think you're advising folks to monitor their authority servers to find out
how many truncated responses are going out and how many TCP sessions result
from these truncations and how many of these TCP sessions are killed by the
RFC1035 4.2.2 connection management logic, and if the numbers seem high, then
they ought to change their applications and DNS content so that truncations
no longer result.

How does the (eventual) deployment of DNSSEC change these numbers?

And who's likely to feel *that* pain first?
