I think you have to go with the Mi Casa Verde Vera 2 controller for remote or local access, or a z-wave stick and software like Z-wave commander http://forums.controlthink.com/t/1669.aspx
but I think z-wave commander only allows control within your home and not remotely.
The Vera 2 offers web access for free but that depends on the company staying in business. The Vera 2 runs $238 on Amazon and on their site.

I have the Trane thermostat with z-wave and was considering the Vera 2 but haven't gotten it yet.
