Yes, simple for one destination but laborious for many.  I was hoping 
there was some way to force it with undocumented environment variables or 
command line options.  For a potential future enhancement, a configuration 
syntax similar to one of the following would be nice:

source s_local { unix-stream("/dev/log-ng" hostname("virtualHostName") ); 
};

-or-

options { myhostname("virtualHostName") ; };

I'm willing to propose a patch if people think it would be of general 
interest.

Thanks,

Bill
