PC Possible to send someone your world?

[Apocalyptical Survivor]

My wife and I play a private game on our LAN and love it. I usually host the game and she Joins. But there are times when I'm not home and she would like to play, without having to start me up too. Is it possible for her computer to get the saved game on my computer and be able to start up the game where we left off and continue it until we play again together?
 



Thanks for any insights or suggestions.
