To the points you made earlier this year, Matt, our small nonprofit works to support the creation of OER courses that are built in Moodle. We have already released a high school chemistry course, described here. We have parts of 3rd grade science course available and are about to release a Moodle course that provides asynchronous capabilities for the Geogebra versions of Illustrative Mathematics's middle school math curriculum. I will post here when that's ready to go (maybe later this week.)
We plan to post these courses and others as they are ready to go on MoodleNet when it's ready to go.
I completely agree that this is a 'sound for a strategy to get more organisations & teachers to adopt Moodle.'
