If you need to maintain the identity mapping you'll have to do so yourself
(e.g. by using a hashmap keyed by identity...). Remote references are
handled for you ok, but copies are not. This is also true for CORBA. The
only middleware I am aware of that maintains identity caching or
"replication" is GemStone's Smalltalk client. But that's quite different
than EJB...
