First ... what is the connection for?  should it work between  
different users on different machines, or is it for a single user on  
a single machine.

If the former, you need to use socket ports and need gdomap running
If the latter, you need to use message ports (the default) and do not  
need gdomap.

That's normal ... because gdomap is not needed/used unless you set up  
a connection using socket ports.

If you need to use socket ports, to create a connection do

connection = [[NSConnection alloc] initWithReceivePort: [NSSocketPort  
port] sendPort: nil];
[connection setRootObject: myserverobject];
[connection registerName: name withNameServer:   
[NSSocketPortNameServer sharedInstance]];
