I suggest using
http://imagemodserver.mine.nu/other/...4autohost2.zip
The simplest way is to share the game folder.
Run the autohost on the local PC, and punch in all your settings.
Create the game, and then have everybody open the shared savegame.
When the turn files appear, it will automatically process the turn, and you can chug through your turns nice and fast.
This would be a simultaneous/separate machines/manual moving setup, but the tool handles the processing.
It can also blink your keyboard lights to show who still needs to finish their turns too!
