Hi Rafael,
At aDeNu (UNED) we implemented ILS for .LRN. It's a simple application (+ portlet + applet) to implement the questionnaire and compute the result to give feedback to the user. There's a callback on questionnaire completion so the results can be used by any application/service that implements the callback.
You can get the code from our CVS (:pserver:mailto:anonymous@cvs.adenu.ia.uned.es:/cvsroot), packages are: ils, ils-portlet and dotlrn-ils.
