You certainly can use the Event service for this.  You could also use
the BiDir plugin.  In our upcoming release of Orbacus 4.2.1 we have
implemented the BiDir GIOP as specified by the OMG in the CORBA 3.0.2
spec.  But for older versions of Orbacus you can simply use the BiDir
plugin.  Basically with BiDir, you pass a callback object from your
client to the server... when the server needs to notify the client, it
makes a request to this callback object.
Depending on your requirements (# of clients, status of connections,
etc...) you might be better off using the Event service.
