How do get access to Interaction Data programmatically

Question

First let me outline what I am trying to do and what my current restrictions are.
Captivate Version: 5 and 6 (but really only 6, they are in the process of upgrading everything to 6)
What I need:
- Access to the Quiz's interaction data for each question.
- I would like to have access to it utilmately in JavaScript.
Restrictions:
- The CBTs are hosted on a SharePoint site that I cannot modify, other than what is possible as a site admin (so no Internal server reporting)
- An LMS is also not an option
My current setup:
I created an aspx page in SharePoint to load the desired Captive file by query string.  I created a JavaScript file to help me communicate with Captivate and capture the basic quiz results (pass/fail, total points, unanswered quiestions, etc) using the cpEIGetValue method.  My JavaScript results function (SubmitQuiz()) is called from the Captivate file on either a submit results button click or the OnPass/OnFail events.  With the result data in JavaScript, I then post (ajax) the results to a SharePoint list using the List web service.
I know I can get each question's answer by having the captivate call a JavaScript method on question submit, but I was trying to avoid that (it means a fair amount of updates to each CBT), and even then I don't think that will give me access to all the interaction data that is provided when you use the internal server reporting method.  Captivate is clearly tracking the data that I want, I just can't find a good way to get to it.
I have spent a decent amount of time researching this and any help with this will be greatly apperiated.

Erik -
Thanks for your reply!
I assumed the internal server meant local server or at least server on the same network, either way that is not an option for me.  The CBTs are in SharePoint, which we don't control and would not be allowed to put an aspx page or other handler to process the post and we arent allowed to setup a service or page somewhere to post to.  Unless if the CBT can post across the internet to a remote server, then its a no go.
I thought have the SCROM approach and rewriting it all, but I have limited time for this and that just looked like a big headache.  I have read the posts on piperworks that show you how to clean up the code, I may have to revisit it at some point, if they really want me to.
I will also see if I can modify the CP calls back to the API, do you know where those are made? Or are they just the OnSuccess/OnLastAttempt actions on the quiz? If so, that is the solution I ended up going with.
Using the JavaScript API, user variables and some advanced actions on the OnEnter/OnSuccess/OnLastAttempt I was able to get pretty much all the interaction results that are stored. The only ones I could not seem to get, were the ObjectiveID, InteractionID and the CorrectReponse.  However, instead of InteractionID I am now using the slide name.  I put a Advanced Action on the OnEnter event of the slide, which is used to set a user variable (v_QuestionStartTimeMS) to cpInfoElaspedTime. By doing so I can calculate the latency in the OnSuccess/OnLastAttempt events (v_QuestionTimeLengthMS = cpInfoElaspedTimeMS - v_QuestionStartTimeMS). The rest of the OnSuccess/OnLastAttempt advanced action calls a JS method.  OnSuccess passes true, OnLastAttempt passes false to the TrackResult function.
I am using the jQuery extend method to load objItem. 
$.Results.GetDate() gives my the date as a string. MM/DD/YYYY
$.CapHelper.GetVariable() a wrapper method I have that ends up calling cpEIGetValue()
$.Results.GetTimeStr() converts MS to HH:MM:SS.mmm string format.
function TrackResult(result) {
    var objItem = $.extend({}, $.Results.Objs.ResultQuest, {
        ResultDate: $.Results.GetDate() + " " + $.CapHelper.GetVariable("cpInfoCurrentTime"),
        SlideName: $.CapHelper.GetVariable("cpInfoCurrentSlideLabel"),
        InteractionID: "",
        ObjectiveID: "",
        InteractionType: $.CapHelper.GetVariable("cpQuizInfoQuestionSlideType"),
        CorrectResponse: "",
        StudentResponse: $.CapHelper.GetVariable("cpQuizInfoAnswerChoice"),
        IsCorrect: result,
        Weight: $.CapHelper.GetVariable("cpQuizInfoPointsPerQuestionSlide"),
        Latency: $.Results.GetTimeStr($.CapHelper.GetVariable("v_QuestionTimeLengthMS"))
    _objResultDetails.push(objItem);
I was hoping for a more elegant solution where I could just get all the data at the end of the quiz, like the internal server reporting option and send it all back at once.  Captivate is clearly tracking all that data, it would be nice if they exposed it so you could do what you want with it.
Again, thanks for your input Erik. I will look into what you suggested as time permits.
