I am working on code, I am going share, when its readable ... and when 
easter vacation is over ;-)
The interesting part in using ly:run-translator is that you can let 
(scheme-)engravers work on your music without actually engraving it. 
Technically this seems to be used for preparing quoted music and other 
stuff, when there is a message "interpreting music" (more than once).
Right now I am collecting music by catching note- and rest-events and 
store it by time and voice in a hierarchical manner. That way I can 
serialize the collected music as lilypond strings and reuse music, 
collected by quoting individual instruments, in a piano part. The result 
has to be adapted in several ways, but at least, I have the right notes 
in place.
And there is another more important use case I will present later, when 
its in a presentable stage.
