Bob, yes you can definitely do this. Dom3 doesnt really care how you "connect" to a game: hotseat, pbem, network. They are all the same to it. So you will be able to start your game up however you like and then continue it when your son goes back to CA.

Once he is there, what you will need to do to continue the game at that point will be to start an instance of Dom3 and set it to be the host server for that game. Then also make sure that you open the correct ports in your firewall (assuming you have one) so that your son can connect to the game host you just started.
