Of course these are guesses, and maybe somebody has better guesses maybe from the 2D examples, but using these for starters I am sure we can look at v2 loa4 visible and find positions where these hand joints look appropriate and operate as expected. 
Then we can work more on the feet.
Thanks,
Joe

Hi Don, I think it is reasonable to expect the same side eyeball, eyelid, and eyebrow all have the same joint center.
