Not really. This is a well known difficulty with area_light being not
truly "area". Most people seem to go for a high 'ambient' in the object
to hide the fact (low diffuse too). A very small 'scale' 'normal' will
help spread the point out as well (must have some specular or phong in
there too).
Everythings a work-around far as I know. The multiple lights might be
too slow, true. But if you try that best thing for smooth shadows would
be a wide 'spotlight' 'tightness 1', just not easy to use for such due
to 'point_at'.
