   I _generally_ view standalone firewalls as a sad admission that   
   end-system designers (OS and App developers) and administrators cannot   
   get their act together.  As such, I hold them in only slightly higher   
   esteem than NATs.  A curmudgeonly old-school point of view perhaps,   
   but then I keep thinking of one of the chapter quotes from The   
   Mythical Man-Month:   
      
     Adde parvum parvo magnus acervus erit - Ovid   
     Add little to little and there will be a big pile.
