Great idea, and a really cool product! I've volunteered for search & rescue work before, and this sounds like a great way to help volunteers communicate. One of the big problems with volunteering is getting halfway decent communications. Just about no one who shows up has a decent map of the area, let alone something like a ham radio, but everyone has a phone. One big question, though - how well does the GoTenna work better with data? Voice, through the regular cell phone system is almost non-existent, but texts can get through much more often. Is it the same with your GoTenna? One other thing, being out of range of a cell tower will quickly drain the battery of a cell phone, as it tries and tries to establish communication using a high-power signal to find a tower. Will the GoTenna look like a cell tower to local cell phones? Oh, one other thing... Is it possible to set up custom groups and send texts to that group? For example, one group of people might be North or you, and another group to the South. Could I send a text to everyone in the North? That would solve a lot of problems... And so would being able to automatically forward text to, say Facebook, to keep the outside world informed.
