I was wondering whether objects serialized using CPython's cPickle are readable by using IronPython's cPickle; the objects in question do not require any modules outside of the built-ins that both Cpython and IronPython include.  Thank you!
If you use the default protocol (0) which is text based, then things should work. I'm not sure what will happen if you use a higher protocol. It's very easy to test this ...
