Ok ... I'll go improve netstumbler instead of laughing ... if there's any traffic it can trivially be detected anyway, so what's the point? Hidden SSID is a hack (which doesn't work with IBSS obviously), but this kinda seems worse. Seriously though, why should the upstream kernel support such bad design decisions...? :) johannes
