It seems to me that this design, compared to conventional crankshaft,
requires much more sophisticated joints, because all movements are
kind of "3D", not like in crankshaft. Most probably it's possible to
make spherical joints up to high standards with today's technology,
but it will be much more difficult and expensive anyway. I am not sure
those will have same life expectancy too.
