I see, thanks for the explanation! I'm afraid you'll have no choice, though, but to relay the message via the local daemon. I know that creates a window of vulnerability, but it cannot be helped.
Passing full contact info for all daemons to all procs would take us back a few steps and cause a whole lot of sockets to be opened...
