Self-Shredding E-Mail

yoink! writes: "I just read an article on CNN.com describing a self-shredding e-mail system. With all the persistent e-mail documents gathered by the Government in the MS Anti-Trust case, and the massive shredding of paper documents by parties in the Enron fiasco, it's no wonder people have been looking for an electronic solution to a material problem solved years ago with some cutting tools, a motor, and a garbage bag." One of the companies highlighted here was called Disappearing, Inc. when it was mentioned a few years ago, but now several others have joined the fray.
