Sounds like you want to broaden the area of the 'grid' of lights.  Best 
results are usually around 10% of the distance to the light source.  If 
you want more softness than that you can have by increasing the area of 
the grid, but need to seriousless increase the 'number' of lights in the 
grid too.  Use 'adaptive' in that case.  Remember this only affects 
shadows though, the highlight will still be a point.  This features gets 
good effects in a broad range of normal cases.  THe serach for 
convincing soft diffuse lighting has lead many to improvise 'dome 
lighting' systems.  Just search the ng's
