Good point about 3rd party moderating.
Seeing the entire game and being able to act on it is one of the reasons I created the "watcher" mod. Its on my mods page.

On my Links page is a link to a thread about game variations which might be useful. I believe that thread also goes into the many things that a GM can "see" about the game from the game logs which makes it easy to check each turn for specific actions you want the game to responsd to.
On my Hosting Games page is a list of possible features that can be added to a game to make it more useful to the players.
