Obtain Quiz results in client side Javascript

I'm trying to obtain quiz results (pass / fail, maybe score) in client side javascript.  The best i've done so far is override the functionallity of quiz.js for the function "player_DoFSCommand(..)".  I have changed the "CC_StoreQuizResults" case to call a function of my own.  I wondering about a couple things here.

1. That function is called multiple times on the last question of the quiz (can create a problem).  Why would this be called multiple times?

2. For what i'm trying to do, is this the best way to go about it?

3. What would be the supported method of acquiring the outcome of a quiz outside the context of the flash file?

Ultimately i want to obtain the results of the quiz on my asp.net server.  My best guess was to get them into my javascript and make an ajax request to the asp.net server. 

Any help here would be greatly appreciated!
