Sorry to confuse you.  My fault.  The boost.python code behind this is 
in a separate repository, here:

   git://gitorious.org/~straszheim/boost/straszheims-python.git

The code has diverged quite a bit  from trunk boost.python by now.
I was only playing with your use case, tossing my results out there. 
Ravi and I discussed the as<...> interface at length on this list some 
time ago, and I've recently resumed playing with it.
