The user would make and record a tutorial entirely in blender, and an interaction text file would be saved.
When a new version comes out, the interactions could be replayed, with the new menu tree, effectively re-rendering the whole video.
Doing so could also allow a user to upload a file summarizing their key bindings, and have any customizations shown in the tutorial.
It wouldn't be perfect, but it'd be neat if it existed.
