- It's important not to settle for mediocre when one can get real security for
- very little money. Specifically, there are encrypting and authenticating
- devices available from various vendors (eg., Racal-Guardata) for reasonable
- amounts of money. Dialback was a solution years ago which has, in the
- intervening time:
-

- 2. been made obsolete
- 3. been talked about long enough to become public knowledge,
- thereby generating much apparent market demand
