Re: Nothing new here
I would really hope that it didn't apply to WPA Enterprise, otherwise it'll be sharing windows login details all over the place.
In small companies it's not uncommon to use a single password (smaller companies rarely have the requisite radius server setup or the experience to run one).
At home of course, it's all passwords. That said, from what they're saying you can detect wifisense users - it's saying they can't access local resources somehow.. in which case you can configure a network to break access for such users (for example redirect the first request outgoing to a local portal... if they don't click OK on that - which wifisense users won't be able to do - then no access).
