Cryptophone

I ran
across a pretty neat new application for the Pocket
PC Phone Edition, which I carry and really like. Cryptophone,
a German company, has unveiled a "secure voice" application that runs on PPC Phones.
From reading their brochure,
it looks like it's a special app that places a data call to another phone (or a PC,
using their software) and allows you to talk with another user. They claim to
have their encryption algorithms totally open so that you can evaluate its strength
yourself. Interesting idea. Also cool is that it comes in a spy-ready
watertight case. I wonder what other kinds of spy gadgets are being developed
on Windows Mobile platforms?
