Want to play spy and use the e-quivalent of disappearing ink? $40 will get you a system that lets you send self-destructing messages through a company called VaporStream.
In a post-Gramm-Leach-Bliley world, will companies actually want to pony up for this, when many are worried about retaining records?
Those who want something free and more integrated should try the Off-The-Record IM encryption project. It works with standalone IM clients such as GAIM, Trillian and Adium X (for Mac OS X). It's pretty darn simple, it scratches that spy itch and even better has deniablility and perfect-forward secrecy.
(Note: Should any software company ever have the word vapor in its title, especially when its announced software isn't available yet?)
