I have a server application which registers an NSConnection using a
unique name. My client application connects with the server by looking
for this connection name, typical DO. But the problem is, I don't want
just any application that knows the server's connection name to connect
to it. I'd like to have some kind of authentication between the server
and client. Is there a built-in method for this, or should I just
implement an authenticating hello message? I saw the
authenticateComponents:withData: delegate methods in NSConnection. Is
that what these are for? If so, how are they used?
