It will be interesting to see a definitive answer on this. But I would just like to make a clarification here... whether the program goes over a LAN or through the Internet, you're still going with the program model of client/server, correct? So for the most part, it doesn't really matter which connection you use. I say this because in order to reach say Google, you'd use the IP of Google, but if you only wanted to connect to your LAN's server you'd use that local IP(192.168.0.xxx). I look forward to seeing a concrete example too, but I don't think it is much different from the previous connection via the Internet... conceptually. And technically speaking, this works the same for SSH. All that matters is whether your client machine is physically on the LAN or not, if it's not then it will not find the local IP, if it is - it will.
