Here is an answer:

http://www.tinaja.com/text/bezchord.html

The description is:

(C) The CONSTANT CHORD method uses 
successive approximations of method (B)
to break the spline up into chords of 
virtually identical length. This method 
is non obvious and computationally intensive. 
But the results are easily distilled and compiled.

If some of the participants in this list have
a reading knowledge of postscript languaje, 
then this is the solution.

Thanks Xavier, Do you have a working example?
The list of coordinates that produces the
bezier handler is uneven. Short segments in
the extreme and long segments in the middle
of the list of coordinates.
I'm not sure how the curve will look like
if you made all segments of the same longitude.
But Don Lancaster has code for this. So lets
wait for an explanation... or translation
to MetaTalk code.
