I'm not too sure the EJB app repository is going to be very useful. A 
server might host numerous EJBs across different applications (1000s 
maybe) and the client(s) might just be interested in just 1 or a few of 
those EJBs. Furthermore, the clients are interested only in the remote 
views exposed by the EJB. Beans that do not expose any remote view are 
of no use in the EJB app repository. Sending down the repository of a 
large number of EJBs (even though it's just identifiers) to each client, 
when the client isn't really interested in most of those, looks like an 
overhead.
