I'm looking into using Mongoose to run the server making things considerably easier for anyone not familiar with installing and running a fully fledged server... besides, Mongoose is tiny and does not require complex configuration...

I will need to switch from a database, to a file based record system, as no database support is included in mongoose by default...

I would ask anyone familiar with MQTT to post comments and suggestions as I have never used it and am somewhat lost as to how to implement it....

Updates:

I have tested Mosquitto (an MQTT broker/server ) using mqtt-spy and it works a treat. Mongoose (small server with php included and support for MQTT) and a replacement for the fully fledged WAMP server appears to works well too but I should note the version I downloaded costs $5...

The next stage is building a web page to take advantage MQTT...
