WARNING_WARNING Under advise from NSA, these features, as currently
WARNING_WARNING implemented, are considered to be not exportable
WARNING_WARNING from the US under the ITAR regulations. Actual
WARNING_WARNING determination is pending legal consul. Even though
WARNING_WARNING we include no encryption technology in Mosaic, we
WARNING_WARNING do provide hooks for encryption and that allegedly
WARNING_WARNING places us under the related materials section of the
WARNING_WARNING ITAR regulation.
WARNING_WARNING
WARNING_WARNING We are working with NSA to arrive at a solution
WARNING_WARNING which would allow these features to be safely
WARNING_WARNING exported.
