This is where you are confused I think. There is no way to send data
to clients if you don't have *any* events on the server. Because how
would you now to send data if you don't have something telling you to
do so? You should have a time event, or a network event from another
client, or a GUI input, or whatever.

It's not totally clear to understand what you're trying to achieve, so
maybe you want to explain more clearly your problem. I suspect you
want to use reactor.callLater, to generate a time event.
