Inverse problem : Can you find a few message bytes in gigabytes of files going back and forth between everyone on the web, or even on an ISP, in order to find a target ? Probably not; at least its tough. Forward problem : GIVEN A TARGET, can you look at all of their traffic over and over until you find their message bytes buried in their traffic ? Much higher probability. And, say, porn to Pakistan will appear in a new light. I would submit that Carnivore from what I have seen deals with the easier forward problem.
