Don's suggestion of the Mozilla weekly status updates (see the main list, and a specific example) I also like. If the reports came out like that (by module: highlights, lowlights, todos, stuff done, etc.), it would be easy to review current status.
My main question about using the SDM is regarding subsystems/modules/packages (whatever they're called). At this point in the game, I think that seeing things explicitly broken out (ie, Query Dispatcher, APM, Installer, BBoard, Bookmarks, etc.) with their statuses, todos, etc. would be a great thing. Can we do that in the SDM now?
