corbaloc/corbaname is a new syntax that was added recently
to the CORBA specification.  The intent was to use something
that looked like a URL, because the web as popularized this
type of syntax for locating resources across a network.

The best thing to do is, download the CORBA specification,
and read section 13.6.10 "Object URLs":

http://www.omg.org/technology/documents/formal/corba_iiop.htm

Read up on the rir syntax for corbaloc and corbaname.  If you
use something like:

string_to_object("corbaname:rir:#MyObject");

This will get close to what you want.   When you start your program,
you could pass it a command-line argument:

myprog -ORBInitRef NameService=corbaloc:iiop:hostname.foo.com:2809/NameService

What this will do is, when your CORBA program calls ORB_init(), it
will put the initial reference for the Naming Service into
an internal table, based on the -ORBInitRef flag which you pass
in on the command-line.

The corbaname:rir:#MyObject syntax for an Object URL tells the ORB to:
     -> look for the Naming Service in the table of initial references
     -> Look for the object named MyObject in the root naming context.

It's a lot of magic, but once you figure it out, it works quite nicely.
