No, Terry, I didn't write that ! :-)

Sorry but this is not even in the neighborhood of what a
properly-implemented IPS does. 

I can certainly see why you think they're worthless though. :-)

`` 'IPS' devices require artificially-engineered topological symmetry-
can have a negative impact on resiliency via path diversity.''
Dang, I thought this quote was from an April 1st RFC when I first read it.

I hate to be the bearer of bad news, but everything we do is "artificial".
There are no routers in nature, no IP packets, no fiber optics. There is no
such thing as "natural engineering" -- engineering is "artificial" by
definition.
You're forgetting that such things are rarely read (in time) by the people
that actually implement and use such a product .. that language is targeted
at the pointy-haired crowd.
Salespeople *hate* it when they get a technical resource instead of a
management one because "it's magic, it's artificial intelligence, etc." just
doesn't fly with us.

Personally I'm of the belief that *all* IPS systems are equally worthless,
unless the goal is to just check a box on a form. Sure they will give you
pretty graphs of script-kiddie attempts but that's just the noise in which
the skilled attack will get lost. You have to do everything else right, you
can't just plug the "magic box" inline and expect to relax.
