I had the Ecobee internet enabled smart thermostat installed over the weekend and so far I'm very impressed.  The full blog on my initial thoughts will be following tomorrow.  I just wanted to release a teaser video.  All I'm trying to show is how the Ecobee thermostat can be controlled over the internet. In this case I used my iPhone with its built in web browser over 3G network (not with the Ecobee iPhone App which is still in development).

Just imagine if I was across the country with my iPhone instead of right next to the thermostat...
