Is this a program that needs to run full time or can it be a couple of days a week?

You can definitely create a hybrid system as I recognize some units in courses lend themselves better than others to this system, so the answer is yes.  It really comes down to the teacher and course material.  I haven't thought much on the hybrid, but at this point I would say that a full unit (or ongoing project) may provide a smoother transition or integration with current practices.
