Well sure, but then you are no longer network transparent. ;-)
oneway/async are hacks that expose the details of networking.
The whole point I was making is that robust remote component usage has
to care about the fact that the component is remote.
For example, there is no reason GConf _can't_ be implemented with
CORBA - but really in the end the IDL _should_ have been something
like:
interface ConfigServer {
oneway void sendMessage (in string message);
}
interface ConfigClient {
oneway void sendMessage (in string message);
}
And CORBA is getting you exactly nowhere there - it's just being used
to avoid fooling with sockets by hand. This is just a traditional text
protocol, with no useful IDL and no useful transparency.
