If he does not have a fixed IP address, dyndns.org allows him to have a permanent domain name associated with dynamic IP address. Many modern modems/routers will automatically update dyndns.org, whenever the IP address changes. In fact I use that when I'm at my Dads, where I want to access my home machine. Whilst my home machine has a fixed IP address, my Dads does not. So I update my firewall rules automatically on my home machine from a script, so SSH is only permitted from my Dad's IP address, not every IP address in the world. I know SSH is pretty secure, but no harm in making it more secure. I've also found 'nohup' useful if running a program from a remote location, as the session does not abort if the connection dies.
