OK, how about:

     1.  Alice prepares an HTML page with embedded Javascript code that
         will submit a DELETE request against the URI
         http://www.example.com/users/bob/ (a resource she has not write
         access to, but Bob has).

Proposals welcome. I think it's worthwhile to mention that RCF2616 is 
very clear about the user agent never to invoke an unsafe method without 
the user's consent, a principle that very clearly isn't followed by 
today's browsers when they allow unsafe methods without any user 
confirmation.
