Not Your Father's TCP/IP Stack
Those days are long gone, thanks to security monstrosities like those depicted next.
My gut tells me that when I see a bunch of terms squashed into one box, it's going to be a mess to understand, inspect, and control. I expect to hear from the development crowd that XML-fu is God's gift to the Green Earth, but it will take a miracle for me to believe that Everything-over-HTTP-over-port-80-TCP is a "good idea." We've got 65535 TCP ports to use and the whole world is collapsing onto one. Argh.
Incidentally, kudos to Cisco for publishing IPJ in such a Web-friendly format, as well as sending free printed copies.
