Does it make sense to add a keyword to the disc syntax (and maybe to
polygon) which will make it orient itself much like area lights do?
With the current faked fire renders by Toni this could partially solve
the problem with reflections and shadows. It could also be used for
incorporating sprites etc. in the scene.

Nice idea, 'orient' keyword for all objects might be interesting.

There is an orient keyword - it's called rotate.

disc {
  <0,0,0>, <0,0,1>, 10
  translate <0,0,-30>
  rotate x*45
  rotate y*45
}

Change the translate and rotate amounts to position it... it will "point" to
<0,0,0>.

  The 'orient' keyword in area_lights does more than just one rotate.

I think he wants it to rotate for each ray that is intersected (like orient
area lights).  That way, shadows from a flat object would not look so flat.
To billboard correctly, you'd have to be able to specify an axis of rotation
(you wouldn't want your trees to fully orient, but only orient about the Y
(up) axis).
