Do you have the even the slightest proof of "impending doom"? Or are you just spewing hysteria that is entirely uninformed by both an understanding of intelligence gathering and any evidence of an actual crackdown?
From a strategic point of view, if the FBI can snoop a router at an ISP, so can the enemy, and the US economy these days depends heavily on the Internet. ISPs are *not* some magic domain of ultra-security that is being invaded by the FBI, they are reeking cesspools of 0WN3D boxes and poorly configured routers. If the FBI can invade your privacy, so can some 16 year old kid in Poland. The third or fourth wave of attacks in this war, if it continues that long, will be against the information infrastructure, and everybody in the business knows this. Expect to see mandatory cryptography for gov't contractors and selected strategic enterprises in a few years.
Crypto is a red herring anyway. The real value of Carnivore isn't the interception of conversations, it's *TRAFFIC ANALYSIS*. Traffic analysis lets you illuminate the entire enemy command structure from a single lead. Just sit back and watch people talk to each other; you don't care what they're saying. This means that so-called "onion routers" and anonymous remailers *WILL* be banned, but not plain old crypto.
Go look at the NSA homepage. What's that you see halfway down the page? Security-enhanced Linux. That's right, the spookiest of US gov't spook agencies is distributing open source security to the world from its home page.
I don't want the world, I just want your half.
