I'm wondering why Vorbis needs any container at all? I know you can stick Vorbis in an Ogg container or a Matroska container, but if I'm not going to bundle it with any video or any other multimedia why can't the Vorbis data stand alone in its own file?
Has anyone had any experience doing this? I googled before searching SO and I only found a single mention in the oggvorbis mailing list with no details.
