I don't know how.  The problem is that the shadow volume algorithm  
involves rendering infinite points, which requires setting yon to  
infinity.  But there is no sensible way to set yon to infinity for an  
orthographic camera.

Yes.  Create a cast-shadows style that specifies not casting a  
shadow.  (Q3CastShadowsStyle_New( kQ3False )) Put this at the  
beginning of a group, and then later objects in that group will not  
cast shadows.
