The only problems I can see with this is, firstly, who assigns it the keyspace focus? That node could be in big troubble if Malory alone gets to assign it. Secondly, even if this does make harvesting IPs more difficult, once you do get a few IPs, wouldn't this make it easier to shut down just those few nodes with such-and-such as keyspace? In other words, I think this may make the keyspace centralize itself around too few nodes. I'm not saying this is impossible, just that I see some problems that any proposal for this would need to solve. > _______________________________________________ Devl mailing list Devl at freenetproject.org http://lists.freenetproject.org/mailman/listinfo/devl
