Because one can cause a surface to glow by using the Ambient channels of the Posersurface/root node in Poser 8/Poser Pro 2010, there has been no further development of the Gather Node (since Poser 7).

To make an aura around an object (instead of making the object itself glow), one needs a transparent envelope around the object (which roughly approximates its shape). That object can be made to glow with the ambient channel (and make it cast no shadow). See the discussion in this thread.
