Interesting.  I wonder how hard it would be to get notes drawn with no stems, 
flags, beams, etc.  We'd also probably want an easier mechanism for entering 
them than switching note head styles, but I guess we could put that off until 
later, and just get it working the easiest way first.

I think I'll sit down and play with this, though I don't promise to get 
anything working.

My thought is to begin by copying an existing style, bent to a new purpose and 
work on the problem from there.  If we can get a duplicated mensural note set 
that happens to come out in LilyPond with a \rest tacked after it, that's a 
beginning.

This does seem like the right solution to me.  Even if we had a permanent 
rest, as I seem to remember suggesting for this or some other problem, there 
would still be no way to reposition it.  If we made it possible to drag rests 
around, then there would still be no way to export that positioning tweaking.

We've said before that LilyPond has micro-positioning too, but unless I've 
missed something, it seems it would be far less than simple to figure out a 
way to convert coordinates in our context to coordinates in their context, 
and so it seems to me that our micro-positioning must remain basically a 
convenience feature, or something to improve draft printing (unless we 
dispose of draft printing.)

Anyway, unless I run into some other problem, it looks like this rest business 
might be the only remaining piece of giving us reasonably usable support for 
multiple voice stuff, if we just acknowledge that chords are impossible to 
solve, and all the notes in a chord will have to be in the same segment, no 
matter how counterintuitive that sometimes can be.
