LED Replacement for LCD projector Bulbs

radiojock asks: "OK, I've got a question -- has anyone ever seen a way to replace a LCD projector's bulb (they burn out way too easily) with the new superbright LEDs ? this should be very possible, take a group of the LEDs and mount them on a board. Would this be able to replace the bulbs? And would the LCD projector manufacturers allow this? Think of the energy savings, and the heat reduction ... Just a thought." I would pay a lot of money for such a replacement bulb, and I suspect a lot of others would too -- which leads me to suspect that such LED arrays really aren't ready yet, or they would be on the market. I hope someone can contradict this -- are LEDs up to the task? I bet the LCD manufacturers would be eager to supply them if so.
