No, the point of the technique is you have a frequency band that you can isolate and use in the background and not in the foreground. Using IR instead of visible as your isolated band makes the isolation easier and cheaper with fewer artifacts and limitations. It's still a very similar process otherwise.
Yes, Corridor's results were great. Fewer limitations would make the process even better!

Alternatively you could use a solid state laser or narrow band LEDs if you need the band to isolate to be in the visible spectrum too.
