With all the talk about the batteries running down, perhaps they need a "Black Box" which just sits there *listening* for some sort of probe signal, before responding with a black-box ping. I imagine that the listening-function would take much less energy than actually generating pings. This would guarantee that you wouldn't be pinging UNLESS someone is in range to hear it.
Has this sort of system been tried? Of course, you could have a hybrid system that would ping for a while and then go into energy-conservation mode and listen for a probe.... -Doug Elrod ([email protected]) -- You received this message because you are subscribed to the Google Groups "World News Now Discussion List" group.
