Well, there are a couple of kludges:

 1. If you are using mayamat.py I can arrange for a scale argument
 which will scale the data appropriately internally (easy to do --
 just change the arange appropriately).

 2. From within MayaVi you can do this by visiting the pipeline
 browser for an actor, clicking on the actor and then changing the
 scale in the correct entry.
  SurfaceMap(Dclick)->ShowPipeline(click)->Actor(dclick)->scale(edit).
