That's been my experience with everything I've tried. World Machine has 
good erosion, but the free version limits the size of the map :( 
Christian Froeschlin has a good idea for making use of the limited 
files. The way POV now handles 16-bit grayscale images makes his idea 
even easier to implement, I think.

Anything can be done, but at what cost? Isosurfaces are already slow, 
and to incorporate erosion... well, I hope you won't be using your 
computer for a while :)

I'd rather make it work with height_fields, but in a more dynamic way 
than it is now. I don't know how to do this yet, though.
