paul121: There's a significant number of people using TheThingsNetwork, however most of those deployments are in towns/cities or require you to trust the way they manage their platform.  I've seen/heard enough about the "private" version to be very concerned, so I'm using my 20 years experience as a systems administrator to build a platform that *should* provide 99.999% uptime and be able to scale rapidly with our customers based on LoRaWAN.io.

As far as MQTT is concerned, another reason for me to be reluctant to implement it as part of the LoRaServer work is that a different approach would be needed to the existing HTTP listener.  We'd need some kind of "worker" that ran in the background, constantly listening to the queue and dealing with messages as they arrive, as opposed to being triggered when a message is posted to a URL.

It's a nice idea though, looks like I'm going to have to brush up on my PHP! :D
