- Sorry, I thought that was clear. Each participating machine has a
- public key and the ability to sign messages.

- That's NOT true, once the secure newsgroup exists: the list of
- participating machines can be posted to the newsgroup! :-O
-
- The list can be amended as time goes on (with each amendment, naturally,
- signed by a plurality of the participating machines in order to be valid).
- You can verify the entire sequence of such amendments, starting with the
- Founding Fathers and ending with the current state of affairs. If you
- haven't been around since the dawn of time, just make sure that the
- signatures of some machines you trust, or a whole lot of prominent people,
- are attached to the list.

- I haven't seen much comment yet. I was expecting, at least, something about
- the pros and cons of using a distributed voting protocol to establish a
- global consensus.
-
- Does anyone have anything to add, or are you all stunned into silence by the
- brilliance of my proposal? ;-)
