I have been reading the WISPA CALEA FAQ and was a little concerned about question #10. If the LEA does not know who the suspect is using an open access point does this mean that everyone that has used that access point will have their data handed over to the LEA? It would seem that if the LEA is only allowed to receive the data requested in the subpoena this would be a violation.
In the past WISP's have asked if there was anyway to keep users from NATing and connecting more then 1 PC. There is no way to block this and no easy way to prevent or detect it. From the ISP perspective there is no way isolate single hotspot user since they all come in on the same IP. If the ISP has control and management of the hotspot they may be able to isolate the traffic of a given mac but this would not be reliable if they connect with a different laptop the next day. Of course it depends what kind of hotspot and how its setup. I would say your going to have to give the LEA all the traffic for the hotspot and let them filter/figure out what they need. Moral of the story: open non-encrypted wireless routers are NOT secure to use. Unless your a bad guy and just drive around tell you find one then do your ill deeds there. Just my opinion.
