yes.
_NTO_CHF_COID_DISCONNECT works for me in the networkcase.
Of courcse my client has a own channel with that flag to get the pulse that the server died.

my client:
[snip]
   /* look for server */
    server_coid = name_open( RECV_NAME, NAME_FLAG_ATTACH_GLOBAL );
    while( server_coid == -1 )
    {  
      sleep(1);
      server_coid = name_open( RECV_NAME, NAME_FLAG_ATTACH_GLOBAL );
    }

    /* We want to be notified when the server goes away.*/
    chid = ChannelCreate(_NTO_CHF_COID_DISCONNECT );
    if( -1 == chid)
    {
        perror( PROGNAME "ChannelCreate");
        exit( EXIT_FAILURE );
    }
    self_coid = ConnectAttach( 0, 0, chid, _NTO_SIDE_CHANNEL, 0 );
    if( -1 == self_coid )
    {
        perror( PROGNAME "ConnectAttach");
        exit( EXIT_FAILURE );
    }
    
    msg.type = REG_MSG;
    
    /* Initialize the sigevent structure (msg.ev) in the message 
     * to be sent to the server.
     */
    SIGEV_PULSE_INIT( &msg.ev, self_coid, getprio(0), MY_PULSE_CODE, 0 );

//send something to the server
    if (MsgSend( server_coid, &msg, sizeof( msg ), NULL, 0 ))
    {
        perror(PROGNAME "MsgSend");
        exit( EXIT_FAILURE );
    }
    
    while( 1 )
    {
        rcvid = MsgReceive( chid, &recv_buf, sizeof(recv_buf), NULL );
        if( -1 == rcvid )
        {
            perror(PROGNAME "MsgReceive");
            continue;
        }
        
        
        if ( 0 == rcvid )
        {
            /* we received a pulse, often a side-effect of using name_attach()
             * we need to deal with the system pulses appropriately 
             */
            switch( recv_buf.pulse.code ) 
            {
                /* system disconnect pulse */
                /* our pulse */    
                case MY_PULSE_CODE:
                	printf(PROGNAME "got my pulse, value is %d\n", recv_buf.pulse.value.sival_int);
                	break;
                
                case _PULSE_CODE_COIDDEATH:
                	printf(PROGNAME "COIDDEATH, value is %d\n", recv_buf.pulse.value.sival_int);
                	printf(PROGNAME "Exiting ...Bye\n");
                	exit(0);
                	break;
