We have the technology. It's a matter of applying those technologies, and they're not cheap. And once you apply them, now your network has probably changed again. So now you have to continually assess that network and continually apply new security features. This isn't cheap.
Anonymity is built into the process.
And in this environment, it's the great equalizer. You know, during the cold war, we knew who the bad guys were, and they had nuclear weapons. There was a finite group, and there was a deterrent, because they knew that if they attacked us, we would know that they attacked us and we would attack them back. That's a significant deterrent. But now, anybody who goes down to Best Buy or Radio Shack can buy a computer for two or three hundred dollars, and they have internet connectivity.
