Well Mach ports are a bit different to a socket, because they're just 
endpoint names (like TCP/IP ports) rather than connection identifiers. 
So it clearly wouldn't work with Mach ports.

Yes, that's right. A UNIX socket is just like a named bidirectional 
pipe.

That's why I thought it might work with the same port on both positions.

Kind regards,
