Actually, thinking about the starting methods, you could put two hall effect sensors close to each other on the same radius, give the coils a kick and see from the hall sensors which direction the rotor is going (one of them will latch first, triggering an interrupt on the micro), the keep kicking it in the same direction or kick it out of phase to reverse it, then once it's up to speed just run it sensorless
