I recently learned about MQTT (http://mqtt.org) a light weight sensor connectivity protocol. Played a bit with it and it looks really cool. The guy who invented the protocol uses it to monitor his house (like way before anyone else) and has a nice presentation (but a bit outdated) about it on Slideshare (http://www.slideshare.net/andysc/the-house-that-twitters).
It's basically a message broker with some publishers and subscribers. Mosquitto (http://mosquitto.org) is an open source implementation of the protocol.
It looks like MQTT is built for things like Flukso sensors so I thought it would be nice to bring up the topic here. I am planning to look at it and see what cool things one can do combining Flukso and Mosquitto but maybe this post can help someone developer who wants to hack something together.
Bart, did you ever consider MQTT for Flukso?
