One mentioned the speed of the IR light and the speed of the N900.

Beside that the camera "can see" the IR blinking of a remote control in visible light (I do not know why this is the case). Just try to make
a photo of a remote control's IR transmitter in action.

So you could mount a mirror at the wall and measure the time
N900 IR -> mirror -> N900 camera.
The problem will be the focusing on the tiny blinking dot and the
speed to measure.
