I assume you're talking about making a "glue layer" that the standard 
Harmony Classlibrary can work with?

TO me, the ideal is to have a very clear demarcation of what is the 
Harmony Classlibrary VM interface.

So I'd see

    Harmony VM Interface
--------------------------

--------------------------
           JCHEVM


Is this what you mean?
