This is a world where you can E-mail sensitive documents anywhere, log in over SSH without a trace, visit cached web sites instead of using "blacklisted" domains, use virtual host names, and set up VPNs. An I.T. person is delusional if he or she honestly believes that it is possible to fully "control" computer use. The solution for securing sensitive material is not to do stupid things like posting it on any web site ("protected" or not), and to absolutely trust under penalty those who receive (paper) copies of it. And so forth.
