E-Mail That Self Destructs: Sending Internet messages that leave no trail.

Forbes reports:

VaporStream, a product for confidential electronic communications, caused a bit of a stir when it was unveiled. When the VaporStream software is installed on a computer or a smartphone, messages disappear from the sender's computing device the minute they are sent and disappear from the recipient's device the moment they are read or replied to. It's not really e-mail, or at least not standard e-mail, although the software is available as a plug-in to Outlook and other e-mail clients. The communication is peer-to-peer, so messages are never stored on any intermediary server the way they are with standard e-mail. The software also prevents messages from being printed or forwarded, and file attachments can be viewed but not saved. Or at least those are the company's claims.

No word from yet from Ezra Klein or journolist members on this one.
