Is it possible to play music from an Android device to Airplay speakers?

I'd like to play my music, podcasts, pandora, etc. on a Libratone Airplay speaker in my house. I bought the Airplay add-on for DoubleTwist thinking it would let me do this, but it appears to only support AppleTV http://www.doubletwist.com/help/question/what-devices-are-supported-by-doubletwist-airplay/ The reason appears to be that there's no UI to select a device in airtwist. Instead, you have to broadcast your availability and then pick the device from the AirPlay device. Sadly, most airplay speakers do not have a UI to select devices. Is there a way to send music to my Libratone or other UI-less Airplay speakers?
