Screenshots are looking great, love seeing the weather bar integrated into the web interface. Looks so good, the design, the clean lines and soft colors, very well done. Can I make a request or two?
* Preference for Menu bar only display, (remove the dock icon)
* On the web interface would it be out of the design to have a second layer of authentication for arming/disarming on the security tab/page, just the ability to have to enter the code to disarm really? (I use the web interface in a wall mounted HD touchscreen, so its logged in all the time which is great for walk up changes etc, much like a command center. The only down side to this is the security can be disarmed without a second password, if it was a jquery keypad it would be 1000% AWESOME!) If it doesn't fit the design or long term goal, I understand.
* Also the Up/Down buttons for thermostats are a little small, even for mouse clicks, but I can live with that.
