We actually need three port numbers - player one, player two, and
spectators (unless you intend that those roles are assigned in order
of connection)

Of course, I think that the server and client should accept the port
numbers as options on the command line, though we could define default
ports.  I envision the possibility of having a tetris meta-server
program that people could connect to, request a game, and have the
tetris meta-server start up a game and say "here are the port numbers
to point your client at".

The DOS possibility via REFRESH is, I think, a good argument that the
server should delay the response to REFRESH until it would send a
response anyway.  Also, it should be specified that the first
diff. sent to any client (especially to spectators) should be a full
board diff.
