VaporStream has released software it claims will not record details
of who sent an e-mail message, or who received it, and so provide a new
level of privacy for electronic communications.

Such software would mean content could remain private and
neither sender nor receiver would be exposed to legal risk from the
communication, the company said. It would also be a means of defeating
the cover-all aspects of compliance regulations and legal discovery
investigations by ensuring private communications remain private.
