Toony Lighted shader only partially affected by light

The default "toony-lighted" shader in Unity is great, but the problem is that objects are either entirely affected by the light, or not affected at all when they are not in the light's direct area.

Is there any way to make it so the object is gradually affected more and more by the light as it moves toward the source, rather than being an on/off type of thing? I don't know too much about writing shaders, I tried switching some of the light modes but that doesn't help.

EDIT: Apparently the toony lighting shader has been re-written in Unity 3.0, and this is no longer an issue. Kudos to the Unity team!
