Eliminate spam through social engineering and nukes - why didn't I think of that? Spam exists because there's money in it, and the same is true for the solutions out there to counter it, extant and to-be-developed. Mankind has figured this stuff out, people - really. DISA will shop, they will buy, and if they choose wisely, they will kill their spam problem and get back to the business of saving the world, or whatever it is they do over there.
