Is it possible to utilize both FFD/Mesh and bones at the same time while animating?

Example: I have a character and the legs and arms are broken into 3 pieces - upper arm, lower arm and hand. But just animating the arm with bones makes them look like a marionette of course because the ends stick out. So I had thought using FFD/Meshes too would hide the "joints" sticking out making them seamless together.

Cheers.

Ok that's great thanks for the input.
