about, from adding a fourth hop to the circuit? Because it would seem
that you need four hops, since the "relay to client-exit" hop isn't
adding much additional anonymity. (Or is it?)
I believe this to be the most interesting question... since the user
does not know his connection will be relayed via a client-exit, there
will only be encryption up until the last relay (the one advertising
itself as an exit). Therefore, even if you re-encrypt the data for
transfer to the client-exit, it will now be *two* hops being able to
read the user's traffic in cleartext.
I don't think that's an improvement... I'd even go as far as saying it's
the exact opposite of what we want.
Plus, having the last relay re-encrypt the connection will add
additional CPU and RAM load, which IMHO is not a good idea.
