Thanks Lev.  That's an interesting method.  It appears that you can actually 
collapse a group while displaying multiple cells.  So I have a method that 
will display all the output cells while "hiding" the input cell:

hideCode[] := (
  SelectionMove[EvaluationNotebook[], All, GeneratedCell, 
   AutoScroll -> False];
  FrontEndTokenExecute["OpenCloseGroup"]
  )

I just call hideCode[] at the end of the input cell I want hidden.  It seems 
to work reasonably well.

Thanks very much,
Januk
