Thanks for the details
...the Bay Web T-stat looks pretty cool from what I've seen about them. I considered them specifically for my house because I love the idea of getting feedback about energy use as well as the occupancy monitors.
In the end, since I'm heat-only, I went with a basic (in comparison) 7-day programmable Honeywell. It works reasonably well, but I know it's less than ideal in terms of efficiency because my schedule is not that rigid, so it ends up running in the evenings when i'm not home.
