As Drupal is mainly a code development community, most of the Kata projects will fall under that realm. Building an open source Drupal curriculum is one of those projects that won't produce code, but will still will take a good deal of planning, time, and money to produce something useful for individuals wanting to learn to companies that may want to re-purpose the materials for their own needs.

As with any Kata project, the curriculum will be
 available
 under 
a
 free
 distribution
 license 
(e.g., 
GPL,
 Creative
Commons, 
BSD, 
etc.)
 and contributed back to the Drupal community. Multiple stakeholders can fund the producers of the content and the entire community and Drupal ecosystem will reap the rewards!

I 'think' that justifies the existence of stand-alone group for this. Now we just need a few good folks to lead the effort!
