I believe this idea has been implemented. In the add assignment screen, the calendar that pops up when setting a due date shows red dots now on all of the upcoming meeting days.
Interestingly, when setting the publish date for individual download and link items on a class bulletin board, the meeting dates are highlighted (as blue boxes) on the calendar. So there's extant code to do this very useful thing!
