  how does FuncDesigner accumulate the derivatives internally?    
see ooFun.py, function _D here  
http://trac.openopt.org/openopt/browser/PythonPackages/FuncDesigner/FuncDesigner/ooFun.py#L479  
   
  
  does it use the reverse mode of AD?    
yes, since the situation for numerical optimization problems where several funcs and much more variables are present is more typical, hence reverse mode is more suitable, as it is mentioned in wikipedia.org automatic differentiation webpage.  
  
You'd better ask the questions in openopt forum, currently I cannot read all the scipy mail list messages.  
Regards, D.
