I strongly agree with this. Real war stories would give real admins a 
better chance of prioritising their efforts to address real problems 
(rather than whatever is currently being pushed by one vendor or another).

In practice, I think a lot of security problems come from layer 8 - if 
you can deal with that, the rest is easy :)
