Hello<br>I want to build a count down clock that will be used for presenters at an upcoming conference.  The important point is that the clock needs to be started and stopped by the &#39;admin&#39; guy, but displayed on one or more screens for the speaker. <br>
<br>My initial thought was to do it in seaside. However, I then wondered whether it would be better to build it all in Squeak.  The benefit of the Squeak approach (I am guessing) is that I could somehow broadcast to the listening images that I wanted them to start/stop, rather than have them polling every second. Obviously, the app is tiny, so in practical terms it doesn&#39;t matter either way, but I am now curious about how I might communicate the start/stop messages over the network to the images.  Is this relatively easy in Squeak?<br>
<br>cheers<br>Andy<br>
