Shell Access
As the preferred method to enter a score is a text editor, any editor can edit the files stored on the server.
If you have trustworthy users give them shell access. They can then compile the lilypond source and produce a .pdf file for printing and optionally a .midi file eg.
lilypond /home/e-smith/files/ibays/scores/mozart/K321.ly
Shell access lets users use all the features of Lilypond, such as importing a .midi file
lilypond --importmidi /home/e-smith/files/ibays/scores/mozart/K123.midi
