ZCatalog is a collection of indexes and metadata, so I don't think
denormalised makes sense in this context. While the OP's problem is
certainly not a trivial problem to solve with only a content-centric index
that is no reason to dismiss the requirement out of hand.

It is possible to get the last login time for a user in Plone (see for
example: http://pypi.python.org/pypi/collective.lastlogin) and from that it
should be possible to query for all content by each user. So long as the
site is not too large this should offer acceptable performance.

Let's keep Plone mailing lists friendly, helpful and constructive, people.
