I'm in a similar situation to you. I bought a Wiimote on a whim after seeing the remote buddy demo video.

I'm in the process of testing different configurations of ir leds. So far I have tried 2 groups of 3, and 6 individuallly spaced leds. The two groups seemed to perform better, presumably because they effectively form a more intense point source.

My next step will be to trial 3 groups of 3, and then 2 groups of 4. The 9 led setup is more efficient to run from usb, so I hope that works out ok.

Will report back what I find.

Regards,
