I haven't experimented with this yet, but I wanted to share with you a set of functions which I've been using for creating analyses for theory classes I teach.  You can find a more recent version (not that recent!) here:

The extension lines you talk about have been at the back of my mind, and I've wondered if there's a way to integrate Lilypond's vast capabilities for figured bass into this system.

A big stumbling block of my approach here has been to allow for a style of input where the user need to include placeholders in the input: so if you wanted to input V/V, you wouldn't need to include a dummy quality marker and a dummy inversion.  Also, there's the question of using note names with accidentals (which these functions do).

You ask about analysis of modulations: somewhere I have a \pivot function which does the Kostka/Payne style arrangement.  I'll try to dig that up.
