A warning about this - even in this case with some ORBs, the IOR will not
necessarily be the same, because some ORBs encode some of the IOR to
include a pseudo-random number to ensure that each generated IOR is
unique. I think Orbix does this, but I'm not sure about omniORB.

The point that I am getting at here is that relying on the IORs being the
same, so that they can be compared for instance, is a Bad Thing, because
I don't think the CORBA standard requires it.

However, if you are just interested in generating an IOR that can be used
to access an object on a particular computer, the above method should
work fine.
