I am the current maintainer because it was lacking a maintainer. I am
in the process of refactoring it to use gstreamer (and get it working
properly on the XO 1.5 hardware) and doing a general code clean up...
I'm somewhat stalled out because of other projects. (Sascha Silbe,
Benjamin Berg, and Sebastian Berg also have been contributing patches
lately.)

Your contributions would be very welcome.
