I'm not sure anyone really ever considered an inside user on a wifi network, however it's encrypted, any different than a user on a regular wired lan... you can sniff their traffic and spoof arp, and all that wonderful stuff.... being on the same broadcast domain necessitates that the machines can speak to each other..... What's the big news here? Was wpa2 supposed to not only provide wire-equivalent security but also prevent arp-spoofing and every other type of switch wrangling? EDIT: I see the significance of this from an internal security point of view - but the choice to use WPA2 is primarily motivated by preventing outsiders from obtaining network keys and gaining access to your network, not preventing insiders from snooping on each other - that's a much different problem.
