drupal learning project

Is anyone already doing this in Drupal?
What services, tool, modules, other resources are you using?
Might you be interested in a Drupal Learning Project?

I had an amazing trip to Cambodia in January of 2010 working with Teachers Across Borders (http://teachersacrossborders.org.au) and considering solutions for professional development for in-service teachers.

We hope to eventually find a way to build a Drupal installation profile to support blended learning and cataloging of learning materials, particularly focusing on lesson plans and classroom materials across multiple languages.
