I thought the networking thing might be more interesting. I was petty sure that each should have a local IP address for the other and if the 2nd machine wants to contact the outside world, numero uno will need to know how to mediate the connection.

Physically, you can just plug them together. If they are gigabit interfaces they will automatically handle the crossover part. And you can use iptables on the internet-connected box to NAT the outbound connections. However, the common and simple approach is to use a home router that will typically provide 4 ethernet connections on the LAN side plus wifi for your phone/tablet/laptop.
