Just don't forget that this really keeps you off the target of opportunity
list some- a determined (or well-equipped) attacker won't mind using
linear amplifiers and high-gain antennas or a chain of cheap and small
repeaters.

Also, denial of service for WLANs are really old technology- so if it does
become critical, you likely won't be able to locate a jammer without
outside help- but that's probably where physical distance helps the most.
