May be not! We could always have had that as a part of the remote interface!
Look at it this way: Push in everything (all the methods) into the remote
interface and have one global home(the factory object that reps. the
container) which will give us a ref. to an RI and then we could do whatever
operations we do now on the home, then on the remote.
In my understanding the point could be more of separating the two different
tasks : "creation/finding" and "business methods" into two different
interfaces. The home interface will do all these life-cycle related things
and the RI does just "business". :)
pl. correct me if i'm wrong,
