I didn't try it, but wouldn't it also be possible to use the vectors
directly, like:

#local c = c0*pow(m,3) + c1*3*c*pow(m,2) + c2*3*pow(c,2)*m + c3*pow(c,3)
camera {location c ...}

AFAIK the slope at the beginning of the spline (at c0) is the same as the
slope of a line between the first two vectors (c0 and c1).
