Ok. If proxy is the way to do it, then it is so, even thaw I still think it's a little backwords. But you have a good point Stefan, of course objects may be viewed as an property of the parent container, and the permissions follows from that.  And of course it's not much of a problem to do the security check inside the python script, the question was ment as to ask if this was the right way, which you clearly answered :P

Thank you all for your comments.

Proxy roles are provided/supported by zope security machinery, where's
the fight?

The only problem with proxy role (AFAICS) is users being able to delete
answers from other users. In your current design the script with proxy
role could (should) check if the current user is allowed to delete an
answer (looking at some attribute). I don't see a big problem.

Well, store all answers from a user in the same folder.
