Hey Alex,
I did some searching and tracked down the thread describing the technique of using the IR filter in the lens assembly:

There is also this one showing some results with a ToUcam II:

I've actually been able to get some nice images without it. I'm really busy looking for work at the moment and will probably be even busier for months starting a new job soon, so this is probably not possible for me in the near future.
Take care,
Doug
