Instead of a conference call in clear voice, how about doing it online from the various meetings, and encrypted? What would it take to set up a broadcast encryption system that will work in chat mode...? A conference call in clear voice is almost certain to be monitored, and I would bet that it would yield a whole lot more high-grade intelligence than we would usually expect: first of all, voices of all participants (for later use in voiceprint recognition surveillance), second, all the background discussions, and third, a lot of the kind of deliberation and working-through-things that ordinarily gets filtered out by the process of posting things to this list. Yes, they can theoretically send visitors to our meetings. But realistically this is more labor intensive and potentially risky than recording a conference call which has all the meetings on line. Let's not go leaving any huge holes, please...! -gg
