Thanks--no, I hadn't seen that. I hadn't thought about using glissando before, 
actually, because it seems to only take arguments within a single voice. Plus, 
I can't seem to start a text span in one voice and end it in another voice.

Would it make sense to, rather than use glissando or something similar, create 
a function that takes a syntax similar to the following:

\lineBegin x y
\lineEnd x y

where x is an index so that \lineBegin and \lineEnd may be matched to one 
another (even across the entire score), and y is the note event (with the 
NoteHead) that the line is drawn from. As a default, I could make any 
\lineBegin that doesn't have a corresponding \lineEnd sets its \lineEnd to the 
same as \lineBegin (so that the length is 0). At the end of the program, a 
scheme function could cycle through each set of pairs and draw a dotted line 
between each pair of coordinates, possibly with make-stencil rather than 
usurping a glissando.

Does this seem like it's at all reasonable? Storing a list of pairs and going 
back later to draw all the lines?
