Just wanted to point out something. When you said Again, right clicking someone and pressing FOLLOW is your PING, not your PID.
I don't know how else to say it other than no way. When you're following someone your character is moved by the server, your internet connection has nothing to do with it. You could lag out and as long as you're still logged in you could be moving.
Also, if you are placed according to your IP, what happens when two people map to the same location? If players were mapped to a hash table based on IP, especially one so poorly designed where you want certain numbers to be lower, a lot of people would be competing for that same spot.
See this from the game engine team.
