WIoTP custom topics

Currently to send a command, you can do it towards one device at the time through MQTT. That kills the whole idea of publish / subscribe model. Would be nice to allow users to use some custom topics, e.g. "custom/notify", so that multiple devices can be subscribed to it, thus making it easier to communicate to multiple devices.

    Hi Alex, Thank you for your interest in the Watson IoT Platform. The IoT platform has been designed with the use of MQTT as one of the communication protocols supported between the device and platform. It is not designed around the general purpose MQTT broker scenario you describe. Your use case can and is solved by a number of our users by having an intermediary application which targets the receiving applications. Amongst other issues this ensures that there exists within the solution a security enforcement point for every message that flows.
