[C++-sig] Extended python system needs access to cPickle in c++

I have an app with a python core, then c++ extension modules.

I'd like to be able to use cPickle to pack structures, especially 
boost::python::tuples, in c++.

Is there a way I can expose a python module in the c++ extensions?

I thought about passing a module as an arg to a c++ function, as a 

// cModule

void DoStuff(object pickleModule)
    tuple t = make_tuple("Spam",42);
    object pickleDumps = pickleModule.attr("dumps");
    object s = pickleDumps(t);

    // Send s to other process

# python
import cModule
import cPickle


Am I barking up the wrong tree?

Many thanks
