It is interesting to note that scanners capable of monitoring cell
phone traffic are illegal in the US, making it hard for the Red team
to go out and buy a unit at Radio Shack and use it to monitor the
Black team's cell phone traffic. Such scanners are available
overseas, at least for analog cell phones, so potential adversaries
could get them. Of course, most US cell phones won't work in the rest
of the world anyway.

A less ambitious project than Starium might be a line of cell phones
with symmetric encryption. You could load the key the same way you
store speed-dial numbers. Three 10-digt numbers would be more than
enough. Several keys could easily be stored. Such phones would
allow small groups to communicate in total secrecy with no additional
infrastructure.
