Has anyone else seen this from Google? https://edu.google.com/products/course-kit/
From their blurb:
"Course Kit allows educators to use tools like Docs, Sheets, Slides, and Drive from within their existing LMS without disrupting classroom management or work flows. Course Kit features a built-in grading tool that allows you to manage feedback all in one central place."
I have signed our school up for beta access; but it looks like a really interesting LTI link between LTI compatible LMS systems (like Moodle) and the Google Education Suite of tools...
