I disagree.  You've left out key steps.

It should be:

1.  Attempt an unmodified attack.
2.  Verify that the IDS responds to it.
3.  Attempt the modified version of the attack.
4.  Verify that the IDS does not respond to it.

In everything that I've seen from both you and K2, you are skipping the
critical steps 1 and 2.  Without them, how do we know RealSecure really
is
failing to detect something? 

This is not rocket science, it's applying the scientific method in its
purest form.

I am not a marketing person.  (Neither is Chris Rouland, for that
matter).  

I am an engineer, and I wrote many of the signatures in the RealSecure
network sensor.

Cooperation is a two-way street.  Perhaps you could tell us exactly
which
exploits you are running in your lab which failed to report on
RealSecure
(steps 3 and 4), and what your control cases were (steps 1 and 2), and
we
could actually answer you properly. 

Just announcing "RealSecure is vulnerable" with no other supporting
details
is exactly as non-helpful as you claim we are being.
