Thought about this for about 1.5 years ago then I was into writing
globaly distributed Java applications using JDK's CORBA with tnameserv.
I find the idea ammusing that you could have a 100% windows application
running on the other side of the globe interacting with your GNOME desktop
using CORBA/IIOP. Anyway you should be able to get any CORBA standards
complicant ORB to speak to ORBit, dont now about OAF thu. By the way
ORBit listens on port 36156 (run 'lsof -p <pid_of_orbit_name_server>'
yourself).
