no, as it takes an ng_socket, and the VERY FIRST thing that is done
when creating an ng_socket is:

        if (suser(td))
                return (EPERM);


There is no distiguishing between message types so once you can send a 
message
(how ngctl gets the info) you can do anything.. it's an "all or nothing" 
thing.

We COULD implement an net.graph.nodes  sysctl that dumps out the current 
graph however..
But it's require someone willing to spend the time to do it.
