[Zope3-dev] Object Status Info

I think it would be handy to have such info available in the ZMI too.

I think some other access mode abstraction could probably be easily
translated.  Really all you need is whether the user who's logged in
(or "nobody") can read/write the object; ftp doesn't really care for
anything else.

If these are the proper concepts in the Zope security philosophy --
I've lost track of the discussion on groups.  Note that ftp really
doesn't require Unix-style output -- that's just the most common form.

Calculated how?

Would be nice to have indeed.  (Though Unix ctime isn't really
creation time -- it's time of last change to metadata.)  I think ZODB
stores the mtime.  The atime may be hard to come by without causing
inefficiencies.

Conceptually it's better to keep this on the object, in case it gets
moved, right?
