Challenges to Opt-Out Privacy Policies at Colleges?

jmaxlow asks: "It's that time of year again when my university sends out mailers informing students that their personal information will be compiled and released in a student directory unless students register objections in writing by the deadline. This info includes name, address, date of birth, and email address, among other items, and there is nothing to prevent them from selling the information to third parties without vested interests. The Buckley Amendment allows them to do this, so of course it isn't illegal. But my question is: has anyone ever petitioned their university to change to an opt-in policy? I'd like to know what responses schools have given, if any, when challenged, before I bring it up with my own registrar."
