Hummingbird rocks, in my experience. It involves a fundamental shift in the way people create and access documents, since it doesn't work with network shares. It also means that you have to enter the meta-data associated with the files every time. However, it does have very strong permissions, access controls, and versioning support, and would likely solve your problem, since you can prevent those who don't need access to a document or project from access, or even viewing that the document exists. On the down side, it's fairly expensive. (In our organization, implementation was at least 5-figures, and probably 6) and it requires a lot of support and baby-sitting (1/2 to 1 FTE, with an organization of about 500).

I'm on the same list as this guy. He is basically a whining, privileged douche, just like all commercial pilots. He is not on the "no-fly" list (otherwise he would not be allowed to fly, period.) The list that he is on is the "Watch" list, which means that he has a name that is the same or similar to someone the government is interested in. What this means is that he has to verify his ID before he gets a boarding pass and pass security. It means that he has to stand in line with the rest of us plebes, rather than walking to front of the line because he's a pilot and therefore exempt from all the hassles that us citizens have to endure. This guy is whining about being treated like everyone else, and having to arrive 15 minutes earlier and show his ID. His job is not on the line, that's just a claim he's making to sue the government.
