At the level of the resultant TCP tunnel (at the application layer, through
an exit or to an onion) all real IP's are effectively anonymized. Tor uses
a mix of PKI, DH, EC, etc in extending its paths and so on. Your
question involves that, ie: does your client negotiate using some
identifiables from that with each endpoint... Take a look at tor-spec.txt
and path-spec.txt.
