Yes, only I can change the email address to which llamaserver passes turns. Also I have no way (or at least I did not found where it is) of knowing the current address the email is sent to, which means once I will want to set you back once you return, I will have to ask your email too (send a PM). That's exactly what slowed Spottygoose (damn, that nickname is contagious!) by one turn
Regarding the copy protection, I think as long as you do not send a C'tis and Atlantis turn at the same time (with the same product key) it shouldn't fire off. If you would do that, I think it would invalidate both turns and simply not do the orders (meaning a stale).
If Shinuyama is still around here, he's a candidate for a sub as well. By the way, I was quite amazed how long he actually survived (and his annoying raiding at south considerably contributed to C'tis's current bad position, I think). Talk about a successful final charge.
