Is there any possibility, any whatsoever, of implmenting a feature that other strategy games have?  That is, if someone joins my game and does not have a save, can the game just transfer the save to them?  Or is there a technical reason why this is not possible?

For instance, if I happen to crash on a game of Civ4, someone can either re-join the game, or if they don't have the save file, that's fine.  I just start up the game, and the save gets transfered over when they connect.  It's a real pain to have to send a save file over to a friend after a crash, if you dont want to roll back to an autosave.
