* have a plugin interface for codecs (gstreamer?)
 * have application specific plugins for effects (basically
  just extend the capabilities of Cinelerra2 plugins a bit
  to include projector and mask)
 * add a LADSPA host (and ditch all hand written sound processors)
 * design the render engine from start as beeing self contained,
  so the render engine (together with these interfaces) is a
  embeddeable component)
 * add the glue language and a small objects/scriptable framework
  at the EDL level, to support things like your track patchbay
  or new editing methods and styles. (thats what I am aiming at
  with the "placements")
 * allow GUI components or extension modules (need to be compiled
  in, but easy to write even for beginers)
