If had be me to write these words I bet my post will be erased, like two of my posts someone censored and deleted here in this "community" forum days ago. Nice!

About plone.protect, yes, it is a nuisance, but the benefits surpass the problems, I think better docs and code examples will help a lot to deal with it.
