Yes--this:
>   (guest schroot) $unset $DISPLAY
should have been:
    (guest schroot) $unset DISPLAY
without the last dollar sign. After running the corrected command:

  $wine ./lmi_wx_shared.exe --ash_nazg --data_path=../data
  Application tried to create a window, but no driver could be loaded.
  Make sure that your X server is running and that $DISPLAY is set correctly.

So $DISPLAY does indeed need to be set, but apparently no xhost liberalization
is necessary.
