Okay, now guess the source.

One of my Hollywood connections to Virtualpolitik and thus a person who is justifiably anxious about nondisclosure issues and/or ownership of valuable intellectual property?

One of my hotshot software sources worried about losing control over proprietary code or a leak that could affect the value of stock prices?

One of the government agencies working on military or security issues that I have interviewed over the years in the course of writing the book?

A lawyer handling a digital rights case involving a gag order?

Someone at the university in charge of student privacy and the custodial control of sensitive personal information?

Nope. None of the above. This message was attached to a mass e-mail to parents from A PUBLIC HIGH SCHOOL with top secret information about the high school exit exam and the dates of Spring Break.
