c-beam MQTT

MQTT is a machine-to-machine (M2M)/“Internet of Things” connectivity protocol. see: http://mqtt.org

We are running a mqtt server on c-beam.cbrp3.c-base.org on port 1883. It's only reachable from the internal network.

An up-to-date listing of artefacts and their topics can be found from https://github.com/c-base/c-flo/tree/master/participants

The content of the current participant folder (updated by running a grunt createMarkup command in c-flo)
