For networking client / server example code you might want to have a
look at the Echo / Echo Client examples found in your
/Developer/Examples/Networking folder. Or perhaps the PictureSharing /
PictureSharingBrowser found in your /Developer/Examples/Foundation
folder, for an example from higher level frameworks. Or check the list
archives. Personally I would probably use something from CFNetwork, and
/ or NSStream APIs.
For communication between threads, you can use
"performSelectorOnMainThread:" for one-way communication from a
background thread to the main thread, or Distributed Objects (DO) for a
two-way link - or pick any old trick from your favourite handbook in C
programming.

I want to spawn a communications server in main.mm

The idea here is that the server start method is a non blocking and
the server puts data into the dataQueue. (And then notifies its parent
thread that new data has arrived.. how I'm not sure yet.)
My question are:
I could have the start method do a fork/exec but is there a preferred
method such as a thread for Cocoa development? (Pointers please).
If a thread is spawned and places data into the queue then is there
any issues regarding a different thread accessing the queue?
Inter thread communications... Is there a Cocoa way?
