Since my ISP implements carrier-grade NAT[1] (with an opt-out system) I read a little about it and found something called the "Port Control Protocol"[2] (PCP). Unless I am mistaken, and *if* my ISP implements it, it seems that it could enable me to run a Tor relay on one of the shared IP numbers.
From what I understand it would make it possible for me to send a message to my ISPs router saying something like "I want an external port bound to this ip:port on my network", and it would either assign a port on the external IP and return it to me, or deny the request. If accepted, I could have my Tor announce that external ip:port and everything should work as expected. Now, before I dig in to this, I wonder if someone else has experience with it? Any flaws with this hypothetical setup?
