Your friend would pay a lot more for the tracking because it will probably require a cellular modem (and GPS) and the battery would last for a week at the most. It is a good idea but not worth it. It is probably best to find new hiding places (:

I think it depends on what the geocaching page has written on it (: For example some people can't physically make it and if possible they want to be included too on the caching log. But if the page says only if you make the climb, then the rules are the rules (:
