Gengyu:

If I understand correctly, you are asking about what happens if a  
node has multiple peer ids in the same overlay. I suspect that you  
might be right that this is a security problem, and if it is, then  
whatever system is being used to generate peer ids must prevent this  
from occurring. As EKR has pointed out, the method if generating peer  
ids is out-of-scope, so we can just assume that the system (whatever  
it is) will take care of it.
