you could always get an animation package and apply the motion capture files your self and then skin what mesh you want to that, then just export the animated x file and the textures, then you have the same as what your asking for.
Once you have a skeleton with animations that can be attached to it, thru motion capture files, it is just like editing a movie. You are asking these guys to include a full animation program. You can do it your self now, if you choose to learn the basics of what you are asking.
