Your trick sounds interesting but I'm not sure I completely understand how it works.

There was a feature I wanted to implement some time ago, it would be sort of an internal server which would directly map to a frontend (or maybe just a backend) without passing via a TCP connection. It looks like your trick does something similar but I just fail to understand how the LB params are assigned to multiple backends for a given server.
