I'm aware of this connection in general, but I'm not really sure whether 
the spline curve segments are necessarily parabolic, or whether that 
only applies to the individual components in a value/result plot; and 
what's more, there's the snag that they can't represent any other conic 
sections. They can't even represent sections of ellipses.
