[omniORB] some beginner questions

[Cristi]

Hi.
I'm new with CORBA and OmniORB and
I have some questions:

1) Is there a possibility to count the number of clients of an object at
some moment?

2) Can be a client refused for some reasons?

3) Suppose you have OmniORB installed on 2 computers and you have an
implementation and you don't know on which ORB of two is registered.
Can you make the two ORBs to communicate so that If you call an object and
you look to host on which the object is not registered, the ORB on this
computer to be able to contact the other ORB and to provide the
implementation requested?


Thanks.
Cristi
