Well I for one would love to be able to walk around inside my scene and pose it literally by hand, at least for setting up scenery like, moving props to create a room say. Or just walking up to LaFemme, taking her hand and dragging it so the IK can  figure out how to get it where I want it. For non-IK body parts, maybe pop up an axis wheel for more precise posing, show the dial panel beside what you're manipulating perhaps. And of course, render from your point of view if you want to.

Heh, ADD CAMERA > VIVE POV
