yes. the FaceTracker (DShow9) is using the same code as the one in the youtube demo.
note the files
addonpack\lib\nodes\freeframes\mesh.idx
addonpack\lib\nodes\freeframes\mesh.tcx
which are mesh indices and texture coordinates respectively. using those you can apply a textured mesh onto the tracked points.
note that the demo has one live-feed and one static image. not two live-feeds which whill make it more tricky, but could still be possible.
