I do however see something like this in addition to the HN post 3 days ago of AirPNP (https://news.ycombinator.com/item?id=7339963). I also thought that was a mock web application at first, but it seems they're serious. Maybe I'm getting too jaded that I don't recognize the needs of the marketplace.
I'm curious how many users you currently have in the beta, if you're willing to divulge the information. Best of luck with executing, and I hope you prove me wrong.
