Quote of the Hour is a shared context publish/subscribe (subscribe only) demo. It's a take-off on the old quote of the day on TCP port 17.
In a real application, instead of a quote, the information would be something that changes unpredictably, and the user wants to always see the latest value.
The demo also subscribes to broadcast messages. The idea is that the broadcast represents some kind of out of band event that the user needs to be notified about. The message is stripped of tags before being displayed, insuring a text only message.
By default, the quote updates once an hour, but the interval is configurable.
