Thanks guys... It looks like ApplicationState objects are treated differently than services... see the bottom of this page "Configuring SSOs":
http://tapestry.apache.org/tapestry5.1/guide/appstate.html I've also walked through the Tapestry code, and there's no binding lookup for application state objects... it simply goes by the class of the object. So it sounds like I'll need to use the contributeApplicationStateManager for my SSO object, and potentially Thiago's recommendation for my second example. I'll play with it tomorrow...
