No no, I know what superoverlays are, sorry I leaved the doubt.

My point with the classification example was not to imply it
was related somehow to regionating, but only to show there is
"features" pressure building on the KML module, this implies
it's getting more and more complex. I just wanted to express a concern
and present an idea (pluggability) to avoid the transformer
class explosion.

Classification was just meant as an example, not as a request for you
to implement it. Same goes for increased modularity of the kml 
transformers, I just wanted to throw the concept on the plate and see
if any bright idea came out.
I'm painfully aware of how under pressure each one of us is, last thing
I want is to overly increase your scope. You're right that modularizing
more KML generation is probably gong to take some sizeable time...
I believe sooner or later we'll have to cross that bridge, but it does
not have to be today ;)

Cheers
Andrea
