You are right and wrong, but mostly right. Sakai has not yet commited to a full open source development philosophy (hence they have redefined the term 'community source' for their own purposes) and the project is midway. The intended new architecture is only now getting seriious attention after a period of merging features from the 4 schools into a CHEF-plus environment.
I agree fully that OpenACS can compete well. My remarks were intended to convey the areas in which I felt OpenACS/dotLRN could improve with reference to a concrete example.
I'll bow out with a reminder that many Universities do research (and other things) as well as teach and that a solution for all of the communities on a University will always be attractive. OpenACS/dotLRN has that potential, but I don't hear it discussed much in the forums.
