Jeff,
Some general comments:
My own formal education in woodworking was via the public school system and was aligned to patternmaking, not furniture making. Over a succession of many semesters we were taken through the proper use of hand tools, primarily chisels and planes ( no sandpaper) and made a succession of "projects", none of which had much utility, but were aimed at teaching particular skills: planing a square edge, planing a flat, chamfering, mortises and tenons, drilling a long hole with a brace and bit, etc, etc. It seems to me that to teach woodworking of a period nature, emphasizing hand tools, you need to first teach people these fundamantals - the blocking and tackling of woodworking. That is a far cry from teaching anyone how to make a particular piece of furniture, but without these skills, one will not succeed at playing the game. The world is full of people who try to start out just "making things" , and this often inevitably leads to disappointment, frustration, and moving on with little learned. While I am not suggesting that you could sustain a class of fundamentals, I think there is an analogy.
An advanced class using very focused fundamantals; emphasis in developing the skills necessary to make a complex and substantial piece of furniture, but without making the entire piece. For example, you might teach the fundamentals of case furniture where student learned to make a cabriolet leg, turned and carved; how to make a single set of dovetails to join a case, how to make a drawer, and how to perform a single particular decorative carving. This could be supplemented by demonstration /lecture written material covering the variations as required for special circumstances. Possibly, the student might make a sample of components for a real piece of furniture to take home as a starting point for a homeproject, but I would try not to emphasize that - the goal is improving advanced skills to be applied generally, and the first try of any of the above projects in not likely to meet the standards of a final product for someone who truly learned along the way.
This could be done a la carte, with a series of one day or weekend sessions, available also one per skill area, so that someone who wanted only a particular specialty, but was not interested in the entire could partake.
I take a lot of continuing education courses ( not in woodworking) and it is my experience that each student is coming from a different background and experience mix, and it is hard to teach a lengthy single course that is well tuned to the needs of such diversity; in order to cover the needs of the less experienced, the class is almost always being held back from the interests of the more advanced. Trying to meet broad needs ends up meeting none well.
