By some (business, not paranoid) considerations, I do not use FileVault2 anyway. Instead, as recommended in this article, I use 7-Zip. The key fature is the compatibility in the heterogenyc network, and others are some matters of business not to be discussed here.But if I can say my opinion, the FileVault2 is an excellent integrated product. And the issues of privacy must be regulated politically, not by just using "right" programs.
