March 2015: On OpenOffice 18.104.22.168 (Linux), this works. The caveat is that the installer does not work. The libraries are stable, though, and integrates well with Lilypond 2.18.2 (current stable).
ooolilypond works nicely
I've got it to work well in NeoOffice 3.x on OS X 10.4.11 ... see the forum threads for fixes.
