Since you're writing out the wave file, it would be nice to be able to
convert existing online material to stored waves that can be retrieved at a
later date to provide "podcast" like capability for listening while
performing some other duty that would not allow you to be hands on. Perhaps
a way to "paste in" content and store rather than have the final result be
short-lived.
