Your analytics should be tracking referring URLss That's something that a JS based analytics package usually tracks.
Yeah, that's most likely the best way to go about it, just a little more work reporting-wise and the normal JS gaps. I was hoping to do something a little more custom and specific with the tracking variable. of course once google indexes the page with the variable in the url it throws off the reporting anyway.
