I do not think repeating what I explained before will be of much help. I never received any responses from my last discussions with Fernando so I am not going to continue that discourse. But here is a brief summary of I tried to explain.
I agree with the part where he focuses on an algorithm for IID generation, but this will have no effect on privacy so claiming to solve the privacy problem by keeping the same IID for a node in a same network is not true. This means that if I do not use a mobile node, I will generate the same IP address until I receive another prefix from the router. He claims this is good for printers or nodes that need a fixed IP address. He believes that having a different IID from the same router prefix does not help with the privacy. But I strongly disagree with this. During the time that the node has the same IID, I as an attacker can easily track this node and, gain enough information about this node, for later when the node comes with a different router prefix, I have more chance to correlate this node with the previous data I obtained from it while it had the IID with previous router prefix. About having the same IID for some nodes, I think that this is really related to the network policy and has nothing to do to with standards but Is more a deployment issue. Currently some network administrators themselves consider this issue so there is no need to tell them how to do this.

I gather that would be in the message at http://www.ietf.org/mail-archive/web/ipv6/current/msg16859.html If there are any issues about privacy you could raise them on the [email protected] mailing list.
