Do You Know UNIX Secrets?

ESR writes "You can help stop the SCO attack on IBM and the Linux community. I'm looking for ways to prove that Unix trade secrets have been legally nullified. I want to know if you have ever had read access to proprietary Unix source code (not just binaries and documentation) under circumstances where either no non-disclosure agreement was required or whatever non-disclosure agreement you had was not enforced. To help out, see my No Secrets page."
