I believe Geo tried something to this effect, with PBW and manually uploading different Components.txt etc throughout the game (every 10-20 turns or somesuch). I don't know if it ever got off the ground or if the 'cheat protection' made it impossible to play in multi. (ie your data files must match the hosts files when the game was created??).
Not sure of much else in the way of details
wish I could help more.
