Well, it all came down to Cisco sending their goons to rip out the
pages from the book given to the attendees of the BlackHat Conference
last week and here's a video to prove it,

(http://www.jwdt.com/~paysan/lynn-cisco.pdf) of the pages that were
ripped out. Now Cisco has a settlement with Lynn that means he has to
dump all of his research in this area. Also ISS has gotten the FBI
involved. To top things off, Cisco/ISS are now sending Cease and Desist
orders to anyone who hosts the presentation photos.
There's also a non-technical explanation of what happened between Lynn
and Cisco which explains it in plain english,
