Animating Spline/Spline Mesh?

Hello All,

I just followed a good tutorial on creating a spline mesh blue print. It worked well, but i need to animate the mesh with the spline. Ideally, i would like to do this with matinee, as i have other objects animating with matinee and the same object. As an example, lets say i want to use the mesh component to create a race track, that i want to animate at certain points, maybe it starts to move vertical etc. At the moment i can seem to animate the mesh object as a whole, not the deformation of the object by the spline.

Matinee is prefered but if anyone knows how to animate this at all it would really help.
