    What does your question mean?  Any port can be safely
    used by any application, assuming the application is
    written securely and the port isn't already in use.
    Of course, to open a port < 1024 you need root
    privileges, so maybe that answers your question?
    If a port < 1024 needs to be used (why, if it's a 
    home-grown app??), the program can drop privileges
    after the port is open.
    
    
    Hope this helps,
