Oh, I like the sound of that! I loved running PBEM games without actually playing in them, so I could peek around and see what all the players did... it's great fun, so I can see where you're coming from.
The biggest problem is, like lch said, that the game makes it so awkward to switch back and forth between turns, so looking at more than a few turns can be pretty frustrating. It should be possible to improve the state of affairs somewhat by using a third party program that allows you to see what the game looked like on turn X with just a click. You'd still need to have all the turn files saved up, though, but that's very easy to set up.
I can see a pretty straightforward way of allowing spectators in a TCP/IP game, though: just run two instances of the game, one for the actual players, and the other one for the spectators. When a turn runs, have the first game copy its files to the second one.
Does that sound like what you were looking for? I know the game doesn't have those two features in a convenient form, but I think it's possible to get a pretty close approximation with a limited amount of hackery. The hackery itself is easy enough to do, but I'm just not sure if it's going to be good enough for what you have in mind. Let me know
