As can be seen on our roadmap sample support is scheduled for 0.4. As this is the major feature, we started working on it. I have to say that building buzztard on top of GStreamer was definitely the right thing to do. We can now load whatever GStreamer can handle. FSM did a nice cairo-based waveform widget. Right now I am working on the code that allows plugins to access the wavetable. It will hopefully be ready real soon.
Besides that I've started to restructure the gst-buzztard package a bit further. I also plan to merge the buzz wrapper plugin into it. The aim is to reduce the number of packages that one needs to build.
FOAF updates: Trust rankings are now exported, making the data available to other users and websites. An external FOAF URI has been added, allowing users to link to an additional FOAF file.
