You're right, the _published_ version of VOP doesn't have them yet. I've
been working on them.
So far, I've got linear splines and cubic (catmull-rom) splines. I don't
know the mathematical formulas for the quadratic splines, and I'm not sure
about the "natural" splines. I have implemented catmull-rom splines, but now
that I've seen them in action, I don't like them (my camera, animated using
a spline, did a strange looping and sudden speed changes). [OT: What kind of
splines would you use for a "fly-through" style animation?]

I'll upload an updated version in the next few days.

Cheers,

Wolfgang
