I've always done this kind of thing with the SocketServer module
and the threading mixin.  You'd say something like:

    from SocketServer import SocketServer, ThreadingMixin

    class Battleship_server(ThreadingMixin, SocketServer):
      def handle(self, request):
        # this method gets called in a new thread when a new connection
        # arrives.  Just handle the whole game for that connection here.

You do need some synchronization to avoid concurrency hazards when
the different threads touch shared data (like a global scoreboard)
but it's not as bad as it sounds.
