Maybe they never thought of it.. I can see a downside, I guess, that if these things continue to get more common and less expensive (a virtual certainty), it could run into a "boy who cried wolf" situation, where any little kid can set up a perpetual SOS on a whim.. still, it seems like such an obvious and desirable feature that someone's bound to do it. Some of the programs in the current Photon III (the power-saving mode) seem at least as complex.<br><br><br>
