remember, its almost 2012, and the interpreter sports full extensibility by 
Python methods these days so you're not limited to the RS274NGC pits any more 
for extending emc - this is not limited to 'scripted toolchange' 

if you get really whacky you'd be able to wrap up mesh probing and model 
computation in a new 'remapped' g-code

another remapped m-code to apply/unapply current model, done

the only 'extension' needed is to write the kinematics module, teach it to read 
HAL pins, and apply corrections

and, of course, come up with a good interpolation algorithm - but there's a 
large body of work there; for instance that is exactly the stuff the GIS folks 
use for map coloring from discrete digital height models
