Yeah I think I've also played multiple nations in the same game from a single machine. This happens sometimes if you are host and one of your players just disappears. You need to go in and set them to AI. I dont recall having any problems with CD-keys, but its been a long time...

You'd think that playing multiple turns from the same machine with the same key would be ok. After all, you are licensed to have the game on that computer - not on who actually plays the turns on that computer. But who knows how the copy protection is actually implmeneted.
