I feel that this project is a great idea generally speaking. You may want to do a little experiment out of it, and perhaps change the criteria a little. For example, 3rd mvt of moonlight is a substantial work, perhaps, if anyone's interested, you could get someone willing to have a few "online" lessons via this forum and choose something around 2-4 pages long, I feel a theme and variation could also work very well here since its clearly sectionalised and with a different element to work on in each. Something not focused on technique but on the musical elements, such as voicing, texture, articulation etc... Beethoven's my fav composer but I would also say his pieces are quite difficult to master in a short amount of time. You could get teachers on the board to give suggestions and have say 2 "online" lessons a week ( a set time to post perhaps) so give the student a bit of time to work at it. It could be interesting to see the results and gather info on what works best.. Of course the most important thing to keep in mind is that people learn differently, and they have their strengths and weaknesses so we could probably only make general assumptions on what works best! Goodluck!!!
