Indeed, this problem is less than trivial.

Basically there are two approaches: 
-- write an 
output routine on the premisse that \vsize=\baselineskip,
so that you always know where you are, or
-- make a two-pass attack on the problem.
-- run the job twice, once with all notes left, once right.

The big K wrote a small piece about this problem
in TUGboat, a couple of years ago. Title was
(I think) `Jill's macros'.
