Sounds like a good idea that needs some financing for the “Rent A Ghost” boys and girls down in the valley. They, a San-Fran-Start-Up called Disappearing, are developing a software based solution that eradicates all traces of your email after it has been sent, resolving many a network administrator’s headache of duplicate copies of both incoming and outgoing mails on their “prized” mail servers.I haven’t worked out whether this company is just sniffing out some first round venture funds after spending all their chump change on doughnuts and dongles. Either way they seem to have an interesting product that I’m sure would have helped those “trusty” folks at Microsoft in their email evidence in the recent Iran-Contra and Microsoft antitrust cases. Hmmmm.The tech behind this little puppy, for those that care, creates a “temporary key for sender and recipient to encrypt and decrypt messages.  After a certain amount of time set by the sender, the “key” will be destroyed at Disappearing’s site and the e-mail message will no longer be readable.” Jackpot.The system “should” be available in the first part of 2000 ... that’s if they don’t disappear when their first cheque clears.
