First there was PGP e-mail. Then there was PGPfone for modems. Now Phil
Zimmermann, creator of the wildly popular Pretty Good Privacy e-mail
encryption program, is debuting his new project, which he hopes will do for
internet phone calls what PGP did for e-mail.
erm, pgpfone worked over IP - it was one of the earliest VoIP packages I ever
encountered, and the very first that used encryption.
