Can this be limited by security? Take our Free Zope server, we don't
want something to discover everyone else's ZCatalog's

What about non-security related? There may be similar instances where
you don't want to discover anything other than a specific catalog...

Also, can an observer that gets notified during discovery just turn
around and so 'no, I don't want to do anything with your notification'?
