I'd love to be able to control my iPhone from an LCD touchscreen monitor. There's a jailbreak tweak that enables bluetooth HID connectivity called BTstack. I need a device to take the USB signal out of a touchscreen LCD and turn that into bluetooth HID signal that the iPhone can understand. Then I could essentially have remote control to my phone. You could also use this to add bluetooth connectivity to an old non-bluetooth mouse. There are a million ways to mirror the phone on a monitor but I want to control the phone on the monitor not look at the phone on the monitor.
