If it goes by WIFI and not the wired network it'll be rather of useless in every enterprise organisation I've ever worked in. I'm not sure I've even worked in a place where the WIFI wasn't a guest network. Don't get me wrong, I'd like the feature. I work in a fully flexible place, but part of that is setting your status to be "working from outside the office" when you're not there. If that could happen automatically that'd be great.
