Wrong. It has a gstreamer driver, it has already been merged into
gstreamer-plugins. There's much room for improvements in that driver,
but it works basically. (What is missing: up to now it's only a sink,
no source. The volume control interface is not implemented yet. The
polypaudio audio clock and latency info is not yet exported to the
pipeline.) It's good enough for Rhythmbox and the like.

What do you mean by "synchronized gstreamer driver"? If that means
that latency and clock info is exported to the pipeline: yes that is
possible. I wrote the Gstreamer driver and I investigated the
gstreamer API well enough to say "yes, that is possible". In fact the
xine and mplayer drivers have already been merged upstream; you get
lip synchronous video playback over the network with both of them. It
werks very well, and effectively it's the same case as with gstreamer.
