* NowPlaying Screen
* NGPSd: a gpsd interface that will show speed, bearing, and altitude in nGhost or icepanel.
* Handsfree support via samr7's hfpd "nohands" work.
* Gstreamer A/V plugin by default with visualizations
Other potential goodies:
* nweather, ntraffic
* revolution skin
In the works for 2.1+:
