I am in agreement with the camp that says to have 2 IR LEDs on one pen would end up looking like a single light. Even if you were to angle them, I don't think you could get enough separation to distinguish 2 separate blobs. But let's say, theoretically, that you could get the IR LEDs to direct their light such that you could get this 20% separation at a given distance away from the IR sensor. You could potentially go further away that this distance, but you could not come closer since your separation would decrees to less that 20%. At any angle, the further away you are from the source, the further the distance the projections would be from each other at the target. The closer you are the closer the projections are to each other. This would limit the usabilty to a given distance.
I know it is neat to have these theoretical discussions and try to find new and creative ways to do thing to try to circumvent the laws of physics and mathematics, but it is always best to keep things simple. When you have tools at your disposal that can do the job (a second Wii controller connected via Bluetooth or the new wireless nunchuck) that aren't restricted by the problems faced using a sencond LED, why not use them?
