Neither geronimo/openejb nor (AFAIK) jboss use RMI/IIOP as the default remote ejb protocol.
 You need to enable CORBA to get this protocol.

yes, that should work fine, and IMO is your best bet for getting this to work.

Theoretically CORBA interoperability should let you use the geronimo corba client to communicate
with the jboss orb.  You'll need to set up the CSS security on geronimo and TSS security on
jboss.  However IMO CORBA interop is mostly a myth.  We test interop between geronimo/yoko
and glassfish but judging by the problems we run into you'd be very lucky to get interop between
yoko and the jboss ORB without fixing bugs in both orbs.  On the other hand I don't think
anyone's tried it so there's always a chance it will work fine.
