He asked me to make a video of the Archvile walking around...Instead I put some music on and made him dance..among other things.
Oh and if you didn't notice, I was controlling specific joints, one in his back(made him stand up straight rather then hunch over) and his neck(twisted it at the end of the video).
The ability to control every joint in a player model dynamically will help a lot when it comes to multiplayer experience and overall realism.
A good example of when this is need: A monster is aiming at a player on much lower ground, it wouldn't make sense if the monster seemed to be looking straight ahead to the player when in fact he's looking directly at the player.
I see a lot of games with this problem. Implementing this would add to the realism greatly.
