I love that idea!!!
I ordered a couple puppy cachekinz, and being a total newbie, I thought they were for my dog's collars. So... that is where they are, and now people can 'discover' my dogs while we are out caching...
Andronicus... maybe you can attach them on your kids backpacks or something... That'd be good too, if they ever got lost in the woods, you could log on and track them!
