I've worked with these products, while at Cylink, and don't think it will
be posible to reach your $100 figure for a standalone device without
manufacturing volumes of 100,000/month or so--even AT&T's attempt at a
similar device was priced considerably higher.  Given the lack of general
population interest it is very unlightly a market of this volume will
develop.  A more likely scenario is the inclusion of this technology in a
digital cordless phone, since the A/D-D/A circuits are already part of the
design--some analog units already include scrambling circuits--although
increased power consumption and therefore either power supply weight or
decreased talk and standby times could become a maketing problem.  If
you're interested go contact one of the many Asian consumer electronics
companies (see http://www.asiansources.com> tell them how many 10,000's of
units you're willing to buy and have them built for U.S. resale.

Again inclusion in a digital phone is easiest and best, but then again its
already digital and if GSM probably encrypted over the air. Cylink's
briefcase-sized SecureCell was never a success (too heavy and expensive).
Maintaining a >9600bps stable modem link via analog cellular still isn't
easy (even when stationary), but has improved with the availability of
specialized modems.  However, you're right that many more users will be
willing to pay and could be a winning combo.  I'm not sure interconnection
of such a device with most miniature cell phones would be a slam dunk.
