Easy now, the sky isn't falling, take a deep breath. TDMA IS monitorable with software, GRE also just released some beta firmware that supposedly does track true Phase II P25. Just because there's a chance of using encryption on this system doesn't mean everything is going to be locked down. As far as I know, I can count on both hands what systems are P25 and completely encrypted across the country.
Clearly there's enough to discuss here if we're already ~17 posts into this discussion. If all you have to contribute to the discussion is gloom and doom, then that's what it'll become. Let's keep it positive and minimize speculation until we actually see where this system is going, it's still early in it's infancy.
