Secure Voice Communications While Travelling?

captnitro asks: "My father works for the US Dept of Commerce in the Eastern Bloc. His hotel room phones are routinely bugged -- a few (former) coworkers have had their stays 'shortened' and politely asked to leave the country, when they said dumb things over the phone. A few days ago he asked me what I use for secure voice when I don't have broadband. Remembering PGPfone from a while back, I looked up the link, but apparently they're no longer supporting/distributing it. While I wouldn't recommend he say much of anything in a bugged room, it got me thinking -- what do *you* use for simple, no-nonsense (requiring modem + sound card), low-bandwidth secure voice app? Unix works, and scriptability gets geek points, but I'll take what I can get."

Voice has a *huge* analog hole - any microphone within 100 ft can pick the converation up, and parabolic dish or laser bounched off the window can extand that range to blocks.

So given that you want to be secure, you *really* have to rule out speach.

So try IM.
