There are already a few pieces of code out there for experimentation with transmission of audio and video information, in a variety of forms/encoding, and probably the most widely used tool, "vat - the Visual Audio Tool", already has provisions for carrying on encrypted audio teleconferences via IP. In fact, it's as simple as typing a key into a field, and the tool will DES en/decrypt the conference. That's a good start! Now all we need something which is a bit more general in its selection of the asymmetric encryption algorithm, and something which does public key for authentication and protection of the assymetric session key. - Ted
