If the ara project is really, "a device running over an internal network, rather than just everything being connected to a CPU," then it would be a great platform for that vision. Presumably, an easy extension would be another device with its own power supply hooking into the network.

Couldn't the power supply be induction?

Sure, but it's hard to induce significant current in devices more than a few cm away. Considering we can't wirelessly power phones in a room, getting the phone to wirelessly power a wearable seems unlikely.
