The obvious question is can you extend the zone controls
to heat only the rooms you care about? Use some learning
system to predict which rooms you care about at which
times of day, motion detectors to allow over riding, etc.

All seems doable. Then you have to ask what is the load
of heating a room from 60 to 72 when someone enters,
does that actually net out a savings over keeping the
room (with furnature, etc.) at a constant value.
