You would have to have a taser license perhaps, and you'd get a discount when flying. Especially if there's a shortage of security people on a particular flight. Airports could have 20 minute courses while you're waiting for your delayed flight anyway. This is normal par for the course, one would just sell it as normal crowd sourcing / uberizing of cabin security. ;)
