I found a way of getting some fun natural movement. This has to be done with the timeline though, wont work with puppeteer. Make sure you have a camera. Point the eyes of your character at the camera (Parameters Tab - General - Misc). Then create a Null directly above your characters head, point the head at the Null and then Parent the Null to the camera (Scene Tab). For the Pelvis, the Null should be below the waste, for the hands, in the general direction the fingers point. Then pin some IK points, change your view to the camera, and watch the magic happen as you move around. To record it, just move the slider on the Timeline and add Key Frames.
