OMG has specified a GIOP (General Inter-ORB Protocol) in order to let
distributed objects to communicate with each other. 
So far the only standard implementation of such specification that is 
available on the market, is IIOP (Internet Inter-ORB Protocol), which 
is TCP/IP plus some CORBA messages. IIOP has been designed to run on 
backbones, to cope with the problem of interoperability of different 
proprietary ORBs.
I'm not aware of existing implementations of IIOP running on IP over
ATM.

There are several implementations of the OMG Corba 2.0 Specs. To mention
just few of them:

Sun's Joe
Iona's OrbixWeb
Visigenic's VisiBroker
ObjectSpace's Voyager 
Netscape and Visigenic's Caffeine (pure Java CORBA/ ORB)

The latest release of the specs is the 2.1.

You could also subscribe to the RMI-USERS@JAVASOFT.COM mailing list
(focused more on RMI than CORBA, but there are several interesting discussions
about RMI/IIOP, that should be included in the future releases of the JDK).

Hope this can help
