Great article, thanks for posting.
While MS working with AMD to use this is definetly newsworthy and REALLY good news for windows admins everywhere(which I once was, before being kidnapped by penguins), this is really good news across the board for every OS that runs on AMD64, including Solaris, Linux, BSD, and any others.
Buffer overflows are a bigtime pain in the butt, and if you look through any OSs patch history, you'll see that tons of those patches are related to just this thing. Man, this is good news, although, I wonder why this ability of AMD64 hasn't been touted more in the IT rags? Or maybe it has, and that news never made it to the rock I live under...
Still, I have to wonder how effective this will be? I guess we'll just have to wait and see.
