Not only won't we discuss it, the carrier (not ST - they're the network operator) will kill any packets coming from anything but the phone, so nothing you can do on your end can make it work. It's not an app problem, it's a "what does Straight Talk allow" problem. If they're not paying the carrier for tethering, you don't get tethering. (And if they did, you'd get it, so you wouldn't be asking.)
