Well, trial and error isn't too bad for this sort of task. Make two
passes down the spline in tiny steps, accumulating the vlength() between
each pair of points. On the first pass simply collect the grand total.
On the second pass, place an object whenever the length since the last
object reaches 1/N of that total length.

My making the steps sufficiently small you should be able to get pretty
good accuracy in reasonable time. I'd guess that a positioning accuracy
of half a pixel would be sufficient for most purposes.
