Hi Matt,
Those open courseware packages look great. I took a look at the MIT stuff and it seems very deep, although you have to install Python to get it to work.
I suspect the problem with all of these open courseware is that they are their own format. Not moodle-ized. Actually, I consider Moodle 2.2 now the global standard, not SCORM, not CC, not IMS.
Using a Community Hub can help teachers share immediately-usable courses on their own site. The Open Courseware will be useful after someone spends 20-100 hours converting the course to a Moodle 2.x course and puts it on a Hub.
Another tool that I forgot to mention, that goes with the Hub, is the Sharing Cart. The new 2.2 version moves individual course items from course to course, almost like drag-and-drop. So you can make a repository of sharable courses on your site, and teachers can come and grab whatever pieces they like.
