Thanks for the answers. I tried the @RemoteBinding approach, and it allows you to lookup beans under an overriding name. Cool. However, JBoss does not let me deploy 2 ejb jars with different versions of EJBs, even if the @RemoteBinding annotations are not conflicting. It says the names are already bound when i deploy the second one. The versioned ear file approach works though. It appears to be better able to provide isolation between apps. Thanks again.
