Well, as a matter of fact, I have :-) For There.com (which simulates an 
Earth-sized planet, shard-less and zoning-less, not using ODE), we 
represent the earth as a cube, inflated to look like a sphere. Each of 
the six faces of the cube then contains displacement data in a regular 
grid. Works pretty well.

Sorry, tangent. I can say that spherical height fields don't matter for 
the floating point version of ODE anyway -- the spheres would be so 
small that you'd notice the curvature too much. (Maybe for an asteroid? :-)
