Hi Hannes,
in my opinion, there is no such thing as full privacy. In that way I do agree
with RJ Atkinson from your above link. Someone has to know where you are in
order to send you packets. What you can do is, to limit the number of people
knowing where you are, in terms of location privacy. Therefore, being partially
anonymous. This, for example, can be realized through some sort of proxy.
Of course, the proxy solution comes at a cost. But the person in need for
privacy may be willing to pay for it (money, latency, etc.). Other nodes, e.g.,
servers may not need privacy and shouldn't suffer from the costs of the privacy
mechanism.
There are two proxy based privacy solution I am aware of. The first is a
privacy location framework for HIP. The second one is my solution.
