Absolutelly sufficient and works :)

Why it is not completely safe? It restricts acquisition somewhat but not completely.

Please read the "Acquistion" section for "explicite acquisition" in <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html> "aq_explicit" returns an explicit acquisition wrapper for an implicit one. Explicit acquisition wrappers still acquire when "aq_self" is itself a wrapped object. Dieter
