Motorola is releasing a new pair of Bluetooth-enabled sunglasses with Oakley called the RAZRWire. Available in three frame colors (all of which are, sadly, still Oakleys), the RAZRWire will presumably work just like a standard Bluetooth headset, except integrated into the glasses themselves (I wouldn’t expect a lens-mounted display, for instance).
