Is there a way to measure the resistance of the IR emitter of the N900 via software? Would it work if it was also emitting IR at the same time?

edit:I once read about this idea of using pulsing LEDs as touch sensors (one of the uses they suggested was for a toggle light switch), they would pulse and then stop emitting and the resistance would be monitored to see how long until the pulse bounces back, if it bounced quickly enough it would mean there is somthing very close to the LED
