        We're always gentle - compassion with a hard edge - to re-coin an
oxymoron[1].

        You need a CORBA impl. at both ends as Rodridgo says - so that you
can pass messages back.

        Very often such notifications would be flagged 'oneway' - ie. the
CORBA method will not (usualy) block, will not wait / allow an exception
or value to be returned. Thus you can quickly fire and forget at all your
clients - without having to wait if one died / blocked in the method.

        Of course, if you use ORBit2 you could use asynchronous method
invocation, but they wouldn't in fact solve your problem.

        HTH,

                Michael.
