    Gil - wouldn't a portlet that displays the user's prefered stock price be
    an example. There you have per-entity (stock portlet) per user (stock
    symbol) state.

    Michael,
    Your inclination towards the "web approach" is largely based on scalability
    reasons - i.e. try to reduce the amount of information the Consumer has to
    store per all entities per all users. To that effect, let me try and
    continue to search for reasons why a Consumer will _have_ to have
    information per-entity-per-user.
    
    In the discussion in the joint interfaces meeting yesterday, I suggested
    that the Consumer would have to store (per-entity-per-user) whether to call
    performAction or getFragment. You, rightly so, told me that you never liked
    the distinction so that this is (not yet) a valid argument.
    
    To tell you the truth, I'm not sure *I* like the distinction between
    performAction and getFragment. It may be that we will have *only*
    performAction, where the action should be _exactly_ the "URL state" you
    mentioned in your point (a) below.
    
    Well, in this case, if the consumer has multiple portlets on the page, it
    _must_ store the "last" action of all of them, and this _must_ be per-user.
    To contrast with the web approach, in the simple Web application, the
    browser stores the application's state in the address bar per-user. In the
    WSRP/WSIA scenario, the Consumer must also store that information,
    per-portlet! This is the only way to allow stateless portlets.
    
    Am I missing something?
