The technology is interesting, but I'm not holding my breath waiting for it to replace current lens designs. I know a few former classmates working with similar technology, and their production costs are staggering, horribly time consuming, and have so far shown a rather poor yield for the quality. (They are however working with the technology for focusing stuff on the xray scale, but everything in the article seems to suggest it is still rather similar.)
But of course one of the awesome things about science is that you never know when a massive breakthrough is going to come. Someone might walk out of their lab tomorrow afternoon with some radical and cool solution to the problems involved, and make an 800mm f/2.8 pancake lens with flawless optics that costs $100.
