That's just a ridiculous article.
I mean I like the idea of a mobile interface to my router but to describe it as an 'app' that controls all the devices on your network.
That aside I guess this could be useful, though if you are using traffic shaping I wouldn't have thought it would be difficult to prioritize business traffic over gaming.
Having to intervene manually by tweaking your router doesn't sound like something most users would want.
I'd like it!
