the nest is a little unique. it can do power stealing if it doesnt have a C 24v AC power wire. you can research that on the NEST forums. i have 3 nests in my house. one of them didnt have the C power so with the extra wire in the cable i hooked it up at the air handler and thermostat.
even though the nest can power steal, it has been know to cause problems with the control board in the air handler, so i wouldnt do it.
as forest said for the wifi based home thermostats, they will i think all require a 24v C power wire.
