We have proposed such a UI for an HP product.  It's based on the user's need to designate the object and method on that object.  For example, a web page might look like

        Resource 1: o Edit <http://foo>     x Read<http://foo>

        Resource 2: x Edit <http://foo>     o Read<http://foo>

        --------

             Delegate Selected Items<http://foo>

Users click on the appropriate link to take some action.  When the user clicks on Delegate, a new web page is shown, which grants access to the selected items.

        Resource 1: o Read<http://foo>

         Resource 2: o Edit<http://foo>

        --------

             Delegate Selected Items<http://foo/>

The URL of that web page is a webkey that can be sent to the delegatee.  A real UI would provide a means to manage delegations.  The key point is that the user does no more work than needed to designate what is to be done.
