Took top-level description I emailed last week and combined it with Clifton's notes to produce a project proposal. Also wrote notes on what features to include in "editable-in-browser" capability, what details we'll need to keep on each course offering to support that and what the implications are for the file structure and GUI features. Sent to Clifton for review. Assuming we go ahead with this project, I'll post those documents to the new blog when I create it.
