I have 4 Thermostats, each fully loaded with remote sensors. I have modified the standard ProntoScript to have a summary page listing my three floors (I have three zones). When you press the button corresponding to a floor on the summary page, you get to a floor page listing the thermostat temp for that floor, as well as all the remotes connected to it (essentialy one sensor per room). On the floor page, there is a button which brings you to a thermostat page allowing you to control the thermostat itself. In case you are wondering what the 4th thermostat is doing, it is not controlling HVAC per se, but it allows communication with additional remote sensors.

I could send you a stripped down version of my file (9400) so you can have a look.
