Christian, just to be clear, in LISP, temporary/ephemeral EIDs can be used for the public case. For a private use case, one uses crypto-EID authentication to regsiter and to get mappings from the mapping database (can be used within a closed user-group VPN). And both for the public and private case, crypto-EIDs can be used so a hash is pretty opaque to trackers. And there is no reason you cannot use a set of private/public key pairs and crypto hashes to send packets.

So there are solutions to this. And they are implmented and ARE NOT complicated.
