This paper shows an approach for adaptive forward differencing of splines with arbitrary order:

sample can now be used to subdivide a spline into a sequence of points which, in turn, form a sequence a lines. An example is given at splines_as_lines.py.

Unlike sample, a toLines must respect discontinuity. Instead of passing the number of desired points (like in sample), it might be easier to pass the maximum distance between two knots.
