Recently PL became playable on Chrome but the controls are very flimsy and hard to use correctly with a combo however the graphics and ping is sufficiently better than the hand -held devices used to play PL. So what I think is that, STS should make an app to allow hand-held devices such as an iPhone or iPod Touch to be used as a gaming controller with Chrome being the high-definition monitor.
Pro's-It feels like your Mac/PC/Linux is a gaming console and many other games on those systems already are compatible with special USB controllers. Since PL has many skills, it would not work unless STS made their own touch-screen game controller app. Instead of guessing which skill is which on the number keys, you will already know from muscle memory when you use your hand-held device.
Con's-STS might charge for it either in plat or money.
BTW nobody payed attention to my post in Baks contest or in the blog section>: (
