"DEFORM to RVK2" copies deform data (except EDGESPLIT,DECIMATE,SUBSURF,BOOLEAN, 
BUILD,MIRROR,ARRAY) of the active object to the RVK (relative vertex key) of
the other selected object.

It is presupposed that the second mesh object is built exactly like the first
one. In fact, it is better to use a true copy with at least one basic shape
key.

The new version of this scrit (Blender 2.43) manages the modifier changes.
There are a lot of modifiers but only the ones which just deforms the shape
can be used : LATTICE, CURVE, WAVE, ARMATURE. You can unset these modifiers
from the script. 

Usage:

Select the object that will receive the rvk info, then select the deformed
object, enter Edit Mode and run this script from the "Mesh->Scripts" menu of
the 3d View.  If the active object has subsurf turned on and nonzero subdiv
level, the script will ask if it should change that.  Before copying data to
the rvk it will also ask whether it should replace or add a new vertex group.
