From what I understand, there's no generic way to probe an I2C bus or SMbus, and therefore any unknown device(s) that are probed with the current code might be accessed in a way that could do anything that we can't predict.
SMBus 2.0 defines an optional ARP-capable device type that can be enumerated (http://smbus.org/specs/smbus20.pdf section 5.6), if I read the spec correctly. I've never seen such a device though..
