I don't think they would apply to POV-Script...their main use is when 
referring to objects by pointers, and POV-Script doesn't have pointers. 
I think that *all* methods would behave "virtual", separate bindings 
would be useless in POV-Script.

I don't see what you mean...why would changing the object be a problem? 
If you mean adding members to an existing variable, then don't do that! 
It would be like trying to add variables and methods to a C++ class. 
Just make a new object from that one, which has the additional members 
you need.
If you mean modifying an object which has been placed in the scene, and 
isn't a variable, then (again) don't do that! Modify the object, and 
*then* put it in the scene. This will work with persistent variables 
just fine...
