SCORM 2004 player for .NET VB (v2)

I have a vb .net web app that runs elearning using a SCORM 1.2 api. I need a royalty free solution to launch and record progress for SCORM 2004 files.? I use VB .NET for my back end so that is what I prefer - unless you are reselling an existing C library. If you take this project on you shoudl be knowledgable in SCORM 2004. In SCORM you will know there is a client side API implemented in JavaScript. The client side API will be detected as the SCORM adapter by any compatible elearning course.? The SCORM API will need to communicate back to the Server so the Get and Set data operations work.? I am looking only for the core technology to be demonstrated and delivered. Setting up courses or users is part of a bigger Learning Managment System? (LMS). So i expect some SQL database tables, a basic launch page to launch a course, the SCORM API to be pushed client side so a course will play, and to see the correct get and sets of parameters going. To be a sucsessful vendor - you will neeed SCORM elearning experience. Any links or demos should be relevant to show an LMS or elearning site.
