Even so...Ascend and Cisco products are still computers. :)

There's a PGP-encrypted audio conferencing program out there I believe.
It just seems like it would require a powerful computer to do it in real
time. Encode data from the audio codec..then encode it again with PGP.

I've heard ways to setup the winsock to dial another individual..setup an
IP in the host file for both IP addresses in both computers. And you
should be able to dial just that one IP. Modem to Modem with the overhead
of TCP/IP. If you do POTS conferencing though, there's better solutions
than TCP/IP.

They would need to know the source/destination IPs to know if they CAN
sniff for a particular person I would think.
