[Building Sakai] Course Management API integration question (now with solution!)

Thanks for mentioning this Jon - it confirms something I've long suspected: that you must implement the whole CM hierarchy, even if your goal is only to get flat course sites into Sakai, like the 'Simple Course Pattern.' Many places in the documentation seem to indicate that you don't need to implement the whole hierarchy, but the code seems to expect it.

I wonder: are there any org using CM in a 'simple' way? If so, how did you address the hierarchy? Or did you just look at CM api and decide it was overkill for your needs (as I had always done)?
