Gustavo, please never ever send a zip file of 4MB to this public
mailing list, your mails got lost in spam folder that I
do not review regularly ..

Interoperability is not defined by the fact you can parse a certain
type of references, but rather through interactions of requests.
PolyORB should work with TAO using IOR ..

First, you'll note that
1/ TAO uses a special API for that
2/ Sun JDK is a very bad example of CORBA compliancy, prefer JacORB
INS works this way
(note in your README file you incorrectly spelt the name of the
./client -ORBInitRef HelloWorld=corbaloc:iiop:
1.2 at 220.127.116.11:1234//000000011Tc7f8f39010dabd4e
(note the corbaloc is the one provided by PolyORB)
Having "Hello" instead of the hexa digits is technically feasible, but
at the cost of a vendor specific
API. It is not planned for now.

You can navigate source code through GPS
