+1 for putting it into AccessControl.

Sounds fine to me.  Maybe the new egg can be mostly BBB shims /
"impedance matching."

+1 for the generic "security tab" stuff.  I'm not so sure about anything
related to the userfolder, though, unless moving it is a huge win.  Hmm,

Before trying the latter, we need to triple check that the zope.index
stuff hasn't bitrotted, or lost / missed any features from the Z2 version.

BTW, making *all* the products seaparate eggs seems like a good plan to me.
