Web controlled Thermostat

I just saw this web site for a internet connected thermostat. I really like the potential of having appliances web connected to the network. There are so many potential applications with these devices.

This device will download a 5 day forcast for your local zip code. In addition, it can connect to remote temperature sensors, and will use the average temperature. (This would be great for us, since the thermostat is downstairs but our upstairs gets very hot.) Also, the thermostat can be configured to send email alerts when there is a tempertature high or low. Also the thermostat can be controlled remotely
