"MIT's house magazine says the idea of using it for chip-borne contraceptives was sparked by a visit by Bill Gates to Langer's laboratory."

Ok.. seriously now... are these people nuts? The device can be turned off wirelessly and there's no encryption and since it's not mentioned, probably no security.

For example: dispensing pain killers. Turn it off or turn up the flow rate... very bad, either way.
