There is a necessary distinction here. For the server I'm writing,
EJBoss, we expect all clients to be Java-based since we're doing webapps
the J2EE. I.e. we will mainly have JSP's and servlets as clients.
For EJB in general, I am not assuming anything. If you want C++ clients
to connect to your EJB-server, fine, choose a vendor whose wire-protocol
supports it. IIOP-support should be a feature just as anything else.
Some support it, some don't. In EJBoss's case we (the developer group of
EJBoss) think it breaks more than it fixes, and we therefore have no
intention of supporting IIOP.
(Note: however, since it is an OpenSource server, there is nothing to
stop anyone interested in IIOP-support to add this)

The Connector API is being standardized through JCP. See the JSR for
more details. A connector will be able to use whatever protocol it wants
to connect to legacy systems. No re-inventing.

If you want to support CORBA-clients, yes. If you want EJB's to connect
to CORBA-systems, yes. The first requires support in the EJB-server, the
second does not.

I too have, very much, an application end point of view perspective. In
order to maximize the usage possibilities of EJB I strongly believe that
choosing one wire-protocol, and one only, is a serious mistake.
