This seems to suggest something similar to where Paul was going, I think 
- that is, findWither should _NOT_ be the vector for creating new DVT 
from scratch. In other words, we have two use cases:

1) I want to make a new DVT
2) I want to tweak an existing DVT

I think it is fair to say that (1) should go through the POJO - as this 
is an operation that is likely to occur at the 'boundaries' (outside of 
the magic Q-MH world).

And if advanced clients need low level access to tweak DVT fields, they 
can do so with a _real_ wither MH (not the mock one we expose now), 
which maybe savior devs could access using privateLookupIn as Paul 
suggested.

What do you think?
