wow. that's pretty pricy stuff. And couple that with the fact that they want you to use a 150 watt metal halide bulb.... your cabinet is going to get HOT FAST!!!
EL wire is much cheaper, easier to use/cut/apply, uses a LOT less power, and creates almost no heat.
Personally, I still don't see any reason to use this other than the "hey I used fiber optics" factor. It's a good idea, but there are much better alternatives.
