I agree.

At the same time, a 'Document' object would be expected to have a 'save'
method (perhaps "commit" would be a good name) which simply makes all the
changes official.  The user doesn't ever HAVE to hit that button marked
Save, but they certainly can.

Now, when you add in Udanax-style version management, the whole usefulness
of saving documents gets a little more doubtful.  I think Tunes should be
based primarily on Udanax algorithms (although probably not code).
Especially since they're unpatentable.
