Thats correct. You could resue everything by just renaming the bean in
the deployment descriptors and the jar-file.
As long as you message bean does the EXACT same thing (i.e calls the
same session bean or has the same message selector) you should not
create a new subscriber - because one of the great thing with MDB is
that you get multithreaded execution of your message listenerns (which
is verry hard, if not even impossible for topics with vanlilla JMS.
