Hello, I've been doing exactly what JEA asks using GWTx (http:// code.google.com/p/gwtx/)... it extends GWT to use java.beans.PropertyChange* which implement all that's needed for the Observer and clientside MVC patterns. As an example for JEA's request you could implement a "user" model that sends a "userLogged" PropertyChange event; all registered views (the apps, in his case) to this event would then update accordingly.
To manage which apps can/can't be displayed an idea would be to use a static singleton registry-like class... A very good source of information for propertyChange support and best programming practices, and my bible for GWT, is the book "GWT in practice" by Cooper/Collins on Manning. Hope this helps, Francesco P.S. It woud be great if GWT implemented natively the java.beans package....
