Only the server sends these updates. Someone with a modem running a server
will have IMHO more major concerns than these.
I don't expect packets to be sent every 5 seconds. I don't believe people
change variables, connect, disconnect and end turns all that often.

If we want to reduce bandwidth we can only send the fields which actually
changed since last time but that requires some extra state to be kept.
