Query: A VIMOS-IFU survey of $z \sim 0.2$ massive lensing galaxy clusters:
  constraining cosmography   We present an integral field spectroscopy survey of rich clusters of galaxies
aimed at studying their lensing properties. Thanks to knowledge of the
spectroscopic caracteristics of more than three families of multiple images in
a single lens, one is able in principle to derive constraints on the geometric
cosmological parameters. We show that this ambitious program is feasible and
present some new results, in particular the redshift measurement of the giant
arc in A2667 and the resdshift confirmation of the counter-image of the radial
arc in MS2137--23. Prospects for the future of such program are presented.
