Hello, I have run a few tests passing values from cPython to IronPython (and back) using a pickled list (in order to integrate .NET-Components in Zope). Unfortunately the results were not as good as expected.
The only protocol that seemed to be useful is version 0 of the pickle-module. Using this protocol I was able to pass a list including some floats, boolean and integer to IronPython, use these values in a .NET-class and return the result-values to cPython. Only strings made some difficulties (insecure string pickle). Protocol-version 1 doesn't work properly. Especially float-values make some trouble. When I unpickle my list in IronPython these values seemed to be adulterated (...hmm dont know if this is the right word :) Protocol-version 2 seemed to be entire useless as I wasnt able to unpickle my list in cPython. I tested the cPickle-module, too. But as expected the results were even worse. Are there any plans to improve the pickle-compatibility in future releases of IronPython? Has somebody else made some other experiences with Pickle/cPickle?

I haven't tried it, but they *should* be compatible. Pickle uses its own stack based language to write out objects - so for pure Python it should work fine. As pickle is a pure Python module which works (I'm pretty sure I tried it back in the past !?!) with IronPython, the semantics should be unchanged.
