This looks great, Boo! Another couple of question for you if you don't mind. If you subscribe to the tracking is it on whenever the unit is on or are you able to turn it off and on at the unit. Is the page you linked supplied by SPOT when you subscribe? Is there any security on the page possible (password, etc.) or a way to turn the view off and on?

With all the things we do in remote areas, hunting, scout camping trips, even when we are scuba diving, I think this might be a no-brainer!
