You may be mistaking rsync for a two-way synchronization tool. It's
not. If you run 'rsync -av $src/ $dst/' any files in $dst that differ
from $src will be overwritten by what is in $src.
You can use the --update (-u) to skip files that are newer on $dst,
which might help you. But if you're trying to keep two systems in
sync and you modify both systems independently, unison may be a better
option.

rsync doesn't care about the file format. It doesn't parse the file
to work its magic.

If you're looking to merge the notecase files between systems, I don't
think either rsync or unison will be of much use. You'd need to use a
tool more like a revision control system (e.g. git) to handle merging
the changes from each system into the other. But there are probably
better ways to achieve your goals than that. :)
