I think if you're looking for a "killer app" in that sense of the term,
DDOSing the root name servers is not going to be the way to do it.

Predicting failure in any complex system begins with an analysis looking
for single points of failure. These could be physical (turning off the
power to MAE West would take down a pretty good chunk of the internet)
or logical.

In the logical category I think the most obvious ones would be if
someone found an effective remote kill for BIND or a flaw in BGP4,
particularly Cisco's implementation.

I've had a hunch for some time that a vulnerability in BGP4 was behind
the L0pht's claim to Congress that they could take down the internet in
half an hour.

FWIW, I'm rather fond of the internet and this is in no way meant to be
any kind of encouragement for anyone to try to attack it.
