From within a remote call, you can execute the following code:

               // ...
               RCF::RcfSession& session = RCF::getCurrentRcfSession();
               session.setOnDestroyCallback( boost::bind(onDisconnect) );
               // ...

, where onDisconnect is a function looking like this:

void onDisconnect()
{
       // ...
}

Using boost::bind, you can pass extra arguments into the callback as well.

As for detecting a client connecting, you can have your clients call a 
particular 
function on the server, to notify the server that they have connected.
