Converting Lilypond to OSC/Midi should be possible. I wouldn't be surprised
if such a thing already exists, at least for MIDI.

Dreaming on, one could imagine having 'player' apps that read a score,
are able to 'hear' each other (by exchanging information on how they
interpret their part of the score), and interact like real musicians would.
They should also have memory, so they can 'practise' a piece and improve
each time they do it. Wonder what such a bunch of 'players' would make
of say, a Schubert piano trio.

The reverse, parsing an OSC stream and generate Lilypond input would be
impossible in most cases I suspect. First, there are no standard messages
for e.g. 'note on', everything is allowed as long as the synthesis code
will understand it. It also the wrong level: at the point your score is
in OSC format, it is already fully interpreted and 'flattened', and the
musical structure is no longer visible.

Sclang is an object-oriented language, and polymorphism is everywere.
As a conposer, you could define classes that represent the elements
of your 'musical language' for a particular piece, and those classes
could contain code that would allow an automatic conversion to e.g.
Lilypond. I guess similar things could be done in LISP with common music.
