In addition, you need a way to react dynamically as the condition or state of the producers and consumers of data changes. INFOD takes into account such situations; most existing systems do not support this. INFOD tells the sources where to send and how to filter information for a particular destination, and the sources and destinations communicate directly with each other. Indirectly, this leads to the subscriber determining what constitutes events at the publisher and which messages should be created in response to these events. (The publishers may do intricate processing on these event message streams before sending messages to the consumers.)

The vision is to tailor content flow and achieve context aware delivery of "Valued Information at the Right Time".
