Sorry, but I am too slow to follow this discussion. alexyz, are you
trying to keep the adversary from maintaining a list of all servers?
It seems obvious to me that in order to achieve that, *any* anonymous
party must not be capable of maintaining such a list. But that
renders at least some servers entirely useless, doesn't it?
In other words, the goal of the adversary here is the same as that of
a legitimate user, only the resources of the legitimate user are far
more precious.
