Author Mesh deform performance problem

In the following example I used C=E9cile Mullers (thanks a lot for the
help) code to deform an ElevationGrid.

My problem here is that the elevtaiongrid is going to be eytremly large
(here "only" 100x100 but 1000x1000 might be required) and each vertex
is going to be moved up to 200 times

In C=E9cile Mullers code the scripts creates and copies a new complete
MFFloat (the heights of the elevation grid in my example with the size
of 100x100) even is only one vertex is going to be moved. So each time
I move a single vertex there is a lot of processing and copying of a
large amounts of data. Data that actually is not affected.

So I was wondering if there is not a way to acess just one Indexed
Vertex and change that without having to "touch" any other vertex, to
increase performance. Maybe with a IndextedFaceSet insead of an
Elevation grid. Or maybe you have other ideas how to improve
performance.
In all other "APIs" I have used so far (shockwave3d/opengl/directx) I
found ways acess and modify just single vertices, but in vrml I don`t
see a solution in vrml from my current horizon.
