Don't do that..

Then fix the config...

Not a feature, use MAC authentication.

Use RADIUS (though the users file should work too).

The socket option has to come first, in fact it can optionally be the
first argument too (as in "chilli_query /path/to/socket list"

I'm busy too, but will review your changes. Patches are welcome,
especially the tested kind.
