The relevance, as I see it, is that the same capabilities used to spy on mobile devices (0-day vulnerabilities/backdoors, or just leverage over telcos) could be used as a de-facto "kill switch".
That said, a law that explicitly gives the state authority to shut down all cell phones in a situation "they perceive" as a risk is an order of magnitude worse.
(The "kill switch" counterpart to JackPair would be systems like mesh networks, ham radio / APRS, etc. GoTenna is one recent commercial product: http://gotenna.com/ http://gotenna.com/ Of course it can probably be easily jammed)
