Please get together with Jeremy, who's done almost exactly this for
Zope 3.  I'm not sure that protocol 2 will be of much help; Jeremy's
code depends on subclassing Pickler and Unpickler, limiting him to
pickling at Python speed (cPickle doesn't allow subclassing and even
if it did, it doesn't have the same internal structure as the classes
in pickle.py; most subclasses I've seen depend on that internal
structure).
