Sensor Area Networks (SANs)

That would be 'C' as in Comfort Units... LOL My pool is 72.08 Comforts!

BTW, the HTTP Post that my gateway sends is only 40 bytes. I'm realizing that it's better to send data periodically then to waste bandwidth on keepalives.

Also, we're not married to the Digi Device Cloud, any device cloud will do and there's several to choose from. I do like the idea of using a device cloud though. Remember this is a mobile SAN. The device cloud acts like a Domain Name Server for XBee internet gateways. As the bus travels across cell site boundaries IP addresses come and go, the device cloud hides the nastiness of all this. WaGu simply passes it login credentials and an XBee name and the device cloud resolves this to a physical location and IP address. The device cloud also provides a pretty slick HTTP/XML interface to do everything we need to monitor and control.
