In Zope 2.7, we're given a choice between C and Python. Could someone point me to a reference on what the difference is between the two?

"C" and "Python" "ZopeSecurityPolicy"s are essentially equivalent. The "C" implementation is faster (thus, you will use this unless you have strong reasons to do otherwise); some products, e.g. "VerboseSecurity", require the Python implementation (but "VerboseSecurity" does not yet work for Zope 2.7). -- Dieter
