Turn a cameraphone into a wireless surveillance camera

Normally we think that people freaking out over the misues of cameraphones is usually unjustified, but we wouldn't blame anybody for being a bit nervous about Chubutokkisangyo Corp.'s new attachment for Japanese cameraphones which is specifically designed for making it easy to covertly spy on other people. Maybe we're off base here, but couldn't this basically be done with a software application rather than having to attach something to the phone?
