Google Tag Manager Plugin + MarketPress Integration (dataLayer)

Would love to see a plugin similar to duracell tomi's that installs Google Tag Manager and is specifically geared to integrate with MarketPress (and eventually maybe CoursePress, Membership 2 and other big WPMUdev plugins).

The integration would automatically generate the required dataLayer, installing the necessary coding onto the appropriate pages to allow for tracking of add to cart, transaction completed, content viewed, button clicked, registration completed, checkout initiated, etc. With the dataLayer in place, it would allow for a much easier configuration of Google Tag Manager, allowing it to pull the correct data during these different events.

Either that, or write an integration for Google Analytics e-commerce tracking and also Facebook Pixel tracking directly into MarketPress (but I think this would be the short term solution.)
