Lilypad for os x social advice

LilyPad is (was) a Mac OS X quasi-real-time previewer for the LilyPond music typesetting system. I never got it anywhere close to where I wanted it to be, and I am currently looking for someone to take over its development or replace it with something new.
LilyPad does not work with current versions of LilyPond, so it’s not even slightly useful anymore.
