could a group play a significant portion of a game in one sitting mulitplayer?
Depends on what you mean by significant. Even singleplayer, midgame turns can take quite a while.
TCP/IP is best for the first turns, and you should be able to crank out the first 20 turns in one sitting. After that, you can switch over to PBW as the turns get longer, and your player's schedules diverge.
