Bul-oney. Only if the sicko knows your kid’s number and is certain it’s in your kid’s possession and your kid is alone and vulnerable. Much easier to do it the old fashioned way of picking a kid wandering alone on the street or at the park.
Any "child" who is old enough to be out "late at night" should be responsible enough that he doesn't have to be connected to Mom by a walkie-talkie.
From your post on the Nintendogs thread:
The other person has to be really close, within the immediate area. When they link up, you can add the other person to your friend list. You do get their profile, and it will alert you to their birthdays and so on. You have to agree to add them, though. You cannot detect location like a GPS.
It’s not just the Nintendogs game, the DS will wirelessly communicate with other DS games within a range of 100 feet or so- but bark mode will scan the area for other users in bark mode, even when the DS is closed- but the game has to be started.
Can other devices with GPS scan also?
Example, general GPS scanning device? A GPS phone scan for a GPS handheld game, Wireless devices? LapTops?
I noticed on some hacker boards, people post looking for ‘hot areas’. Does that work with handhelds? Phones?
