Please take a look at: http://anonsvn.jboss.org/repos/jbossas/projects/ejb3/trunk/injection/ I'm rewriting the injection framework there. Note that the JavaEE 5 client specifications already solve most of the problems you describe. With the new clients you can do: @EJB MySession session; to get a reference without JNDI calls. I don't know about the caching part. It's easier to have every injection do a JNDI call, then try to differentiate which calls won't create a new object and which calls do. The usual client application will most likely cache SLSB references anyway. A public ServiceLocater might be nice to get references to EJB's based on interface. With the last item you mean: having the client use services located on difference hosts? That would be cool. It's in violation with JavaEE 5 spec though so we need to clearly separate it from a regular JavaEE 5 client.
