exporting variables to be read in a Google docs spreadsheet

I'm being asked to show a non-LMS method to gather gather data from Storyline courses on learner progress (something that gives us more data than Google Analytics, which would only look at the page where the SL "object" is contained).

I'd like to implement one of these "non-LMS" methods to capture some data. Right now I just need to show something to mgmt like a proof-of-concept. My thought is to just have a couple of variables for a small section of a course...."slide1complete" to "slideNcomplete" and then a "Section1complete"...all set as booleans and the triggers to mod them to Y once the timeline for that slide (or last slide) completed.

I understand the create vars in SL, probably some javascript in user.js, and the google spreadsheet that contains a script to get the vars and print them.

Does anyone have anything like this already minimally completed that I could repurpose? Or someplace where the entire process is documented cradle-to-grave (I've read the referenced blog posts in the forum posts here that discuss the process but in order to "beat the clock" I need something that I can mockup quickly).

thanks,

John
