The snsd is not really magic. It only changes the routing of Apache.

Backend. When an instance starts, it registers with the snsd. Every  
time a new session (+ ID) is created, this is registered with the  
snsd. So snsd always knows which process is driving which session.

Frontend. Every time Apache (mod_ngobjweb) receives a request (with a  
session-id), it asks the snsd for the instance port maintaining that  
session. Well, and routes the request to that instance.
