Yes. NSPort is part of the Distributed Objects system. It's possible to use NSPort on its own, but you must use it to talk to another process which also uses NSPort. It is *possible* to use NSSocketPort to create a socket which you then communicate with using other techniques, but you can't use NSSocketPort directly to talk to a non-Cocoa app. > If so, where in the process do I > squeeze those in?

You'll have a pair of NSStreams which wrap the same socket. When you write to your NSOutputStream the data will be written to the socket, and when the other end writes to the socket, it will appear on your NSInputStream.
