Yes, I know this problem, in particular if the quoted voice is already quite 
low, then stem UP would be okay withouth collisions to the rest shown above...

AFAIK, there is no easy way. The cue substitution (i.e. the sections with cue 
notes are replaced by a music expression containing the cue notes and the real 
notes) is built in quite deeply: in scm/music-functions.scm, function cue-
substitute, where make-voice-props-set does exactly the same as voiceOne... 
You would have to sneak in a \override Stem #'direction = #UP somehow, but 
don't see an easy way to do so :(

Yes, I think I wrote that a long while ago for one of my orchestra scores.

I don't think there is a way to find out the author (unless you are an LSR 
admin...)

Not that I know of.

They went quite well (although the whole audience comes from an audio 
background, so classical music notation is not that interesting to them). The 
video recordings of the talks will be made available in the next few weeks.

BTW, Han-Wen made a lasting impression a few years ago at LAC. I talked to a 
few people, who remembered him and his talk where he compared the different 
flat 
signs and how ugly the small differences in other commercial editions are (not 
that the audience cared a bit about these differences... After all, they are 
mainly audio developers and artists, not music publishers). But his enthusiasm 
for his personal passion left a really positive impression.
