The full disclosure versus bug secrecy debate is a lot larger than computer security. Matt Blaze's article on master-key locking systems in this issue (page 24) is a case in point.

But the most interesting part of this story is that the locksmith community went ballistic after Blaze published his research on master-key lock vulnerability.
Bruce Schneier (Sat,) studied this question.
