Just an aside to your discussion, obviously, but...

What about using a regular pigment function in the height field? Or a pigment
function called at <x,0,z> in an isosurface? (Not strictly a heightfield but
you get the same effect.) Or, of course, you could always write your own
heightfield macro...

As always, plenty of ways to skin a cat... :)
