Thanks to all of you for your very helpful suggestions and inspiration.
  Lots to do!  As an aside, I'm going to adapt some of these approaches
to a computer music class -- which typically  has 6-8 students.  I
think I'm going to have them learn a certain application in twos.  All
this is very stimulating.  Best, Anna
