In reply to Justin Reid:
The manufacturer and vendors could handle that. Then when you get a piece of gear stuck, you'd just need to run DMM CragSwApp, scan the tag and register the item as abandoned. Nearby climbers would then receive a push notification with details of the gear to their phone, and if they swipe right they will see a map with directions to the stuck piece (including route beta). Once they've recovered the piece, they can register it as belonging to them (using the app again). If a piece of stuck gear is found abandoned, but not registered, then the registered owner would be in for a fine for littering.
