This is obviously "tease 'em in-the-shadow-of-Satan" marketing, but it is
in the nature of things that a few hundred clever kids will sit down to
write comparable software after they read this announcement.  Now consider,
what percentage of real threats come over the Net, and what percentage are
homegrown <behind the firewall> among disgruntled employees?

Suerte,
        Vin
