Great, that seems like it ought to work. Do you have a source for this, so I can give credit where credit is due?

@mikeazo: Yes, I could use SSL to get secure channels. Broadcasting is possible but inefficient, since it just means transmitting to everyone. The threshold of corrupt players should be "better" then in the my naive approach. Assuming a 1% chance of leakage is tolerable, 30% of actors may be corrupted (in my naive approach), so better than that.

@rath: What I mean by "hard-coded value" is something like cat(IP address, nonce), where nonce is the number of times you've generated a random ordering. The nodes then go in order from smallest to largest, as you suggest. The point is that any participant can verify that the ordering is correct; otherwise an adversary with only four nodes could just put themselves next to you!
