@Dal, the exporter, Tower of Babel, is in the extensions.  Shape key groups for morphing have been done for a while.  Vismes are getting close.  The skeleton interpolator is not operational.  I did use it in a test scene recently.  No skeleton or actual talking, but exercising the FACE & WINK shape key groups.  The Eyes are using a rotation POV animation. I have abandoned motion capture in favor of inverse kinetics inside of Blender.  Not sure when this will be done, sorry.
