Perhaps eventually. It's something we've looked into, but we have some content security concerns. Obviously it's not impossible to rip our content with flash streaming, but it is more difficult than something that can be written with an <audio> tag.

Someone could easily steal my car's stereo even if I lock the doors, by using a slim jim/lockpick (downloader tool) or smashing my window (rip audio straight from the sound card). There's no way to 100% stop determined people from stealing my stereo, just like there's no 100% way to stop determined people from ripping our content. But that doesn't mean I leave my car unlocked.

Also right now we use the flash piece as a proxy for making service calls that would be otherwise significantly more difficult/impossible through javascript's crossdomain restrictions.
