While the xmpp backend works really good, I've had no problems during the last months, there were very little sensors, basically just my own and - from time to time - some roamers.
As such service is pretty worthless without users, I thought about how to make it more attractive.
The best thing I could come up with, was allowing all sensors to receive files streamed to the xmpp channel, so your benefit from contributing to xmpp is getting something back.
