Venstar Insteon Thermostat Adapter

There's some discussion on this device at the Smarthome message boards and it's not know exactly what it supports, extra humidity or temperature sensor or remote fan control? The developer of Indigo has indicated that the final release of Indigo 2.5 will support this device.
It's hard for me not to run out and pre order it right away. The cheapest Venstar Thermostat is $70 and the adapter is $99. It might seem expensive but the TXB16 thermostat is $300.
