title: Multi-bitrate/dynamic rate for progressive FLV playback
body: <p>Is there a way to get multi-bitrate playback working with progessive playback without having to download all versions of the file? People all coming up with all kinds of cool ways to make progressive feel like streaming. I wouldn't be surprised if there is also a hack for this. Any module names or reading resources that people in the know in this field can recommend?</p>
